Given the scale of these challenges, the BRGM can only applaud the wealth of exchanges and debates that took place during the Grenelle Environment Forum. The conclusions of this nation-wide consultation have not only confirmed the relevance of our priority topic areas - contributions to the safety of underground CO2 storage, geothermal energy development, groundwater monitoring, coastal erosion problems - but are also encouraging us to speed up the pace of planned changes and redeployments that are already well under way in some of our departments. The BRGM has become a hub of French research in the geosciences, and we are also pursuing our partnership policy with universities, local and central government authorities and agencies, and with European and international cooperation programmes. The mineral resources sector is a case in point, and we poised are to scale up our efforts in this field. We are already involved in a great many contract-based programmes, with the European Union, the World Bank, or with companies such as Total, Mitsubishi, Areva and Eramet. We are also contributing to the development of new multilateral mechanisms, especially those geared to furthering knowledge on resources in Africa. We will be paying close attention to international negotiations on the new rules of governance that must be implemented in a context of sustained price rises and increasing concentration of business activity. 1 BRGM > AN NUAL REPORT 2007 > PAGE 02 2 3 Concerning information systems, and data interoperability in particular, the BRGM had already anticipated the social demands that were clearly expressed during the Grenelle Environment Forum. One of our objectives is to guarantee transparent access for all audiences (central and local government policy-makers, industries and the general public) to all available georeferenced information produced by the BRGM or other organisations. Efforts to this end are being undertaken with many different scientific and institutional partners, including the INRIA, DGME, IGN, IFEN and ADEME. In France, the BRGM is one of the key organisations involved in transposing the European INSPIRE Directive. The BRGM has become a reference institution in the field of groundwater. For the purpose of implementing the EU Water Framework Directive, we are setting up a piezometric monitoring network across France on request from the Ministry of Ecology’s Water Directorate, the Water Agencies and the new Water and Aquatic Habitats Office (ONEMA). In parallel, we are studying climate change impacts on the quality of underground water reserves and on water table replenishment. We recently completed a three-year contract with Saudi Arabia, where the objective was to assess the quality and usable resources of the country’s deep aquifers. 2007 also saw the phasing-in of the post-mining activities which the BRGM, on request from the government, was dissolved to take over once the state mining company, Charbonnages de France, was wound up on 1 January 2008. Activities within the Mine Safety and Risk Prevention Department (DPSM), which we established for this purpose, have grown rapidly, and about a hundred staff members 4 5 6 7 “ The Grenelle Environment Forum has confirmed the relevance of our priority topic areas. ” Philippe Vesseron Chairman and Chief Executive Officer were recruited to the BRGM to fulfil this new role, mainly with the four Territorial Post-Mining Units (UTAM). These structural changes account for a quarter of the exceptionally high rate of growth in BRGM turnover in 2007 (+20.8%), which was essentially due to strong demand, both in France and abroad, for our services in practically all of our topic areas. Resources from research contracts increased by 31.6%, while our public service and international activities also grew, by 25.1% and 51.6% respectively. Divisions 1_Ch. Fouillac Research Director 2_L.

Guérillon Secretary-General To conduct all these activities, we give particular emphasis to sourcing new skills, and in 2007, the BRGM again recruited heavily among younger people. In this respect, like all other geoscience establishments in France and elsewhere, we are increasingly confronted with the need to match skills to new requirements. Developing initial and continuing training is of paramount importance in rising to the challenges of the future. 6_P.-L. Kircher Financial Director 7_G.

In September 2006, Thierry Chambolle was appointed to the Chair of the BRGM’s Scientific Committee. Previously, from 1978 to 1988, he headed the Ministry of the Environment’s Directorate for Water and Prevention of Pollution and Risks. He then took up the post of Director for technological development with the Lyonnaise des Eaux Group, before joining the Suez Group as delegate for innovation and the environment. At the same time, he held the chair of the CEMAGREF (1989-1999). In the last five years, he has produced several reports commissioned by the government*. Your many responsibilities over the course of your career have placed you in an excellent position as an observer. What are your thoughts on the Grenelle Environment Forum? Thierry Chambolle: Although I did not take part in the forum myself, I followed events closely, particularly on behalf of the Academy of Technology. All those who took part in the forum (ecologists, industrialists, union representatives, experts and civil servants) were fairly satisfied with the outcome – an achievement that was by no means a foregone conclusion, and for which tribute is due to Nathalie Kosciusko-Morizet.The next stages will obviously be more problematical: for example, how is the aim of 20% of organic agriculture in France to be achieved, given the complexities of the current situation? My one regret has to do with the economic aspects. Eco businesses, yet again, were not represented, so that no true strategy for developing eco-technologies and eco-business in France was able to emerge. Thierry Chambolle Chairman of the Scientific Committee, Member of the Academy of Technology “ If the BRGM didn’t exist, we’d have to invent it! ” An open-cast mine. © BRGM im@gé BRGM > AN NUAL REPORT 2007 > PAGE 08 How do you think the conclusions of the Grenelle Environment Forum will affect the BRGM’s strategy ? Th. C.: I accepted Philippe Vesseron’s offer of presiding the BRGM’s scientific committee with great enthusiasm, having previously been a member of the board for 11 years, at the time when the BRGM was mainly a holding company for the mining sector. Since then, the BRGM has successfully undergone a profound transformation to adapt to the challenges of today. My enthusiasm for the post lies mainly in the BRGM’s unique position in France, since it combines research with public service responsibilities and an important role in international cooperation. The Grenelle Environment Forum has recognised that our planet is vulnerable, that It is unique, and that it cannot continue to withstand the pressures of its rapidly expanding and increasingly developed human population.This is most obviously apparent in climate change, but The BRGM is closely involved in issues relating to CO2 storage underground, and was one of the main organisers of the 2nd International Symposium on CO2 capture and storage held in Paris on 4 - 5 October 2007. © BRGM im@gé - P.Desbordes the anticipated depletion of fossil energy sources and some mineral resources and the threat of water scarcities are also bringing current patterns of growth into question.With the Grenelle forum, an attempt has been made to draw conclusions and to put forward possible policy changes. As a geosciences organisation, the BRGM, because of its role as a specialist on Planet Earth - almost in the medical sense - is obviously closely involved through its cutting-edge activities on issues that range from underground water reserves to mineral resources, CO2 storage and natural risks. If the BRGM didn’t exist, we’d have to invent it! So the BRGM has a tremendous responsibility? Th. C.: Yes indeed, the BRGM is taking centre stage on many of the major policy and scientific challenges facing Europe today, including climate change and looming scarcities of mineral, energy and water resources in the face of increasing demand. The decline of mineral resources needs to return to the forefront among the BRGM’s concerns. In recent years, facilities supporting this topic area have been diverted to other priority areas, such as water, risks or geothermal energy, mainly because of France’s low potential in the mining sector. I believe that the BRGM’s strategy should renew its emphasis on mineral resources, while correlatively developing its work on recycling, one of our traditional areas of competence. In an entirely different field, activities on geothermal energy from deep and shallow sources need to be pursued further. The Grenelle Environment Forum clearly showed that housing offers the greatest potential, in the short and medium term, for leveraging reductions in greenhouse gas emissions. Shallow geothermal energy is probably best suited to achieving significant reductions in energy consumption for heating purposes, and the BRGM can provide technical support to businesses involved in heat-pump development. Deep geothermal energy is more a matter for fundamental research. The BRGM’s multidisciplinary nature is undoubtedly a real asset in this context … Th. C.: Most certainly. To take just one example, if fuel cells are mainstreamed into automobile production, we will need to produce 300 times more platinum than we do at present. Conversely, other new technologies can help to avert the risks arising from the depletion of certain mineral resources. Essential technological responses to current and future challenges generally require highly integrated multidisciplinary approaches, and the BRGM’s involvement goes to the heart of these issues. * Reports on new energy technologies (2004), on eco-businesses (2006) and on governance in European research (2008). BRGM > AN NUAL REPORT 2007 > PAGE 09 Perspectives ENVIRONMENTAL INFORMATION: A CHALLENGE FOR GOVERNANCE In the last ten years, the BRGM’s voluntarist policy for free information distribution has enabled us to satisfy both policy-making requirements and the demands of public debate. Loïc Beroud Director for Public Services “ We have anticipated on current policy guidelines that require maximum transparency in the publication of information....... ” 7.3 million visits in 2007 to the BRGM’s data distribution sites on the Web. BRGM > AN NUAL REPORT 2007 > PAGE 10 “Establish the production of, and guaranteed access to, environmental information as a public policy in itself to support environmental assessments”: this is one of the main recommendations in the conclusions of the Grenelle Environmental Forum, which the BRGM can only applaud. For some 10 years now, the distribution of geoscientific and environmental information has been a core component of our public service activities. “Our mission in this area covers all the expert assessment activities carried out by our departments for all stakeholders, and public policy-makers in particular (in central and local government departments and agencies), as well as for soil and subsoil monitoring activities at all levels”, explains Loïc Beroud, the director for public service activities. Over and above our traditional responsibilities (geological mapping and collecting data on all drilling activities in France), the BRGM has, over the years, established numerous geolocated information systems in its various areas of competence (mineral resources, groundwaters, natural risks, contaminated land, geothermal energy, etc.) at national and regional levels. Web searches are growing exponentially These efforts have produced some thirty freeaccess databases and associated web sites. The exponential increase in the number of searches on these web sites clearly reflects their success. “We’ve gone from 300 000 searches in 2005 to 3.73 million in 2007, not counting the Géocatalogue”, says Loïc Beroud.The “Géocatalogue”, which went on line in 2006, is the section of the “Géoportail” produced by the BRGM, and record- ed almost as many visits in 2007 as the other sites put together. However, the sheer volume of on-line information has raised two new problems. The first concerns access to the information, which has to be both simple and relevant: users need to be able to obtain the information they need, and only that information, as quickly as possible. The second problem concerns the multiple sources of information: here, the idea is to ensure that from the user point of view, access to information, produced by the BRGM or others, is not only “transparent” but also in accordance with the roles and responsibilities of each information source. Géor@pports for decision-support Here again, the BRGM began to invest in new technologies at a very early stage, especially in the area of data interoperability. It contributed to the development of the European INSPIRE directive and was one of the first French public organisations that successfully brought the interoperability concept into practice: in 2006 and 2007, all of the BRGM’s georeferenced information systems were brought into compliance with the new standards. A particular example is InfoTerre, a cartographic platform for access to the BRGM’s geoscientific data (http://infoterre.brgm.fr). Also of note is the BRGM’s experimental programme on our innovative “Géor@pports”.These “Geo-reports” are synopses that are automatically compiled online from the full set of information stored in the BRGM’s databases. Users can request a Géor@pport at any time, on a given issue (subsoil structure, risks, presence of water, etc.) in any given zone. “This concept is an outstanding decision-support tool that could easily be applied to sources of public information other than the BRGM”, says Loïc Beroud. As well as its traditional fields of expertise, the BRGM has thus acquired a new area of competence in information systems. Loïc Beroud points out that “10 years on from Version 1 of Infoterre, our priorities are fully in line with the political will to offer systematic online access to public environmental information”. THE GEOSCIENCE PROFESSIONS In an overall context of insufficient recruitment to scientific training, the geosciences are no exception. The BRGM is in a position to address this situation with constructive proposals. The current lack of motivation for scientific studies is affecting many other countries besides France. In fact, notes Jacques Varet, the BRGM’s director for forward studies, the problem seems less acute in our country than elsewhere, such as in the United States. Nevertheless, there is an urgent need to raise awareness of this problem among young people, their families and the teaching professions, and to promote the “teaching-research-industrial partnerships” triangle. 220 Masters’ Degrees in France Boosting interest in mineral resources The contract for 2005-2008 between the BRGM and the State is designed to deliver sustained activity, full staff mobilisation and expanded sub-contracting opportunities. “Looking at our mid-term review, we have to recognise that the BRGM is up against the problem of a lack of well-qualified geoscience professionals, whether in terms of internal staffing needs or external secondments from public (mainly academic) bodies and private organisations (engineering consultancies, overseas partners, etc.)”, says Jacques Varet. Qualified students are opting for sectors like banking or insurance, rather than aiming for scientific careers, which have been losing their attraction. A more detailed analysis of the geosciences professions shows considerable differences between topic areas. In the last few years, qualified geoscientists have mainly been attracted to disciplines concerning the environment and planning (including risks, waste management and coastal management). “In France, recruitment to disciplines concerned with mineral resources has been virtually at a standstill, with the exception of oil and, more recently, uranium”, explains Jacques Varet. The situation is now critical, given that most of the BRGM’s staff in the mineral resources and energy sectors were recruited in the 1970s and will soon be retiring. Calling on the European geological survey network This trend is not only apparent in France. Almost everywhere, there is an increasing attraction for environmental professions, while the image of the extractive industry is losing favour. Similarly, there is a severe deficit in training capacity despite the current boom in the A wide range of careers has opened up in the geosciences. © BRGM im@gé extractive sector fuelled by the growth of emerging countries such as China. In France, relevant training programmes, as well as the required facilities, are also highly dispersed: only 37 of 220 Master’s courses are likely to be of interest Jacques Varet to the oil industry. Forward Studies “It has become important to and Assessments Director show that subsurface resources are a component of sustainable development,” says Jacques Varet, The BRGM is a major who adds that careers need to be employer in the geosciences field, made more attractive, both for interfacing between public French and foreign students, and scientific research and expert host programmes for foreign studies to support students should be boosted. The policy-making and business BRGM has made several proposdevelopment. als, including the establishment of an internationally recognised geosciences faculty at the University of Orleans. It is also prepared to encourage senior or retired staff to contribute actively to training programmes in higher education establishments.

Total current operating expenses and income 2007 After deducting expenses carried forward (¤0.34 million) and the renewal of reserves, total pre-tax current operating income for FY 2007 amounted to ¤112.6 million, up by ¤18.88 million, or +20%, compared to 2006, while comparable expenses, at ¤106.05 million, increased by only +¤13.06 million, or +14% over the previous year.

Resources from contracts also continued to increase (+31.6% for scientific research, 25.1% for public services and 51.6% for international activities). These results produced a gross operating surplus of ¤10.4 million as against ¤4.7 million in 2006, an excellent result that enabled us to implement the current profit sharing agreement with an overall bonus of ¤1.02 million, taking applicable ceilings into account. FY 2007 therefore produced an atypical operating surplus of +¤6.5 million, as against +¤0.7 million in 2006. +20 % in turnover in 2007 ie ld s rf he *including post mine research (cf.GISOS) and expert studies (GEODERIS) Ot M et ro In lo fo gy rm at io n sy st Po em st s -m in in g – DP SM W at M er in er al re so ur ce s* Na tu ra an lr d Co isk w n s as ta te m m ina an te ag d Ge em lan ot en d he t rm al Ge en ol er og gy ica lC O2 st or ag e Ge ol og y 3.72 The financial result was positive at ¤3.1 million compared to ¤2.1 million in the previous year, mainly thanks to increased interest invoiced to our subsidiaries (+¤0.63 million) and higher income from investments in securities (+¤0.26 million). The write-off of certain prescribed expenses, our annual flat-rate tax liability and an exceptional positive result of ¤1.37 million produced a net accounting income of ¤11 million. The balance sheet for 2007 shows a significant increase in circulating assets and liabilities, which is partly due to an increase in our activities and partly to a change in the way these are presented. Results for our subsidiaries in FY 2007 were influenced by a change in the electricity sale price applied at Géothermie Bouillante after agreement from the CRE, which produced an operating surplus of ¤1.9 million as against a loss of ¤0.7 million in 2006, and a positive net accounting result of ¤0.76 million compared to ¤0.02 million in 2006. Along with five other public target-oriented research bodies (CEMAGREF, CIRAD, IFREMER, INRA and IRD), the BRGM comes under Programme 187 in the Organic Law on Public Accounts (LOLF) managed by the Interministerial Task Force for Research and Higher Education (MIRES ). Under this programme, State allocations are divided into 8 activities, with activities 1 to 3 grouped together under “Scientific research allocations” and activities 6 to 7 under “Public Service allocations”, while activity 8 covers joint facilities.

Among these contracts, resources from those with economic objectives eligible for the Carnot scheme (contracts with businesses, local authorities and water agencies in France and abroad) increased from ¤3.91 million in 2006 to ¤7.81 million in 2007. Contracts with the National Research Agency (ANR) earned an additional ¤0.78 million in 2007, most of which was allocated to skills sourcing (theses, etc.). PUBLIC SERVICES 40.17 In France International 6.71 16.01 SERVICES 22.72 POST-MINING (DPSM) 7.58 BRGM > AN NUAL REPORT 2007 > PAGE 14 In scientific research, the high rate of growth in contract resources (+74.3%) confirms that the BRGM’s strategic research policies are well suited to sustainable development concerns that attract national and international funding. The creation of the ANR in 2005 began to produce significant effects in 2006 and 2007 (about ¤2 million in addition to the Carnot scheme). Grants from the European Union’s Framework Programme for Research and Development (FPRD) amounted to some ¤3.6 million in 2007.The other main clients for these co-financed activities were local authorities, the ANDRA, ADEME and industrial partners. Contract resources from public service activities (observatories, methodological support,training and expert studies) grew by +54.6%. This was achieved thanks to a significant increase in partnerships with target-oriented agencies (water agencies and ADEME) and local authorities, and in new commissions from government departments financed under specific agreements (observatories, and methodological support plus expert studies on post-mining for the MEDAD*).

Growth in this activity area in 2007 related mainly to access to geological data (from information systems especially), to information on contaminated land and waste, geothermal energy and, to a lesser extent, coastlines, groundwater and post-mining. For the third year running, programme financing from contracts was in excess of government allocations. 120 scientific publications in international Class A journals Growth in our international activities was particularly strong in 2007 (+70.3%). This high growth rate and the nature of some of the services undertaken considerably expanded our calls for subcontracting. In 2007, industries (mining and petroleum) accounted for 50% of our international activities. Multilateral funding remained high at 42%, including from EU sources such as FED/SYSMIN, which provided over one third of our international income with about ¤6 million; financing of this type will peak at about ¤9 million in 2008 and decline substantially as from the following year (to ¤3 million in 2009 and ¤0.6 million in 2010), as the last calls for bids for were issued in 2007. The geographical distribution of our international activities confirms the growing importance of Africa (88% in 2007), which accounted for only 20% in 2002 and 55% in 2005, followed by Asia, Europe, the Maghreb and the Middle East. 2007 saw the completion of the technical components of a major contract with the Kingdom of Saudi Arabia on modelling of the Saq aquifer, on which a third of the Kingdom's population relies (completion was expected in 2008). A ¤2 million contract was signed with Slovenia for geological, geotechnical and seismic studies prior to the installation of a new nuclear reactor.The BRGM,leading a consortium that includes the IRSN and Slovenia's geological survey (GeoZS), won the contract against competing American and Japanese tenders. BRGM > AN NUAL REPORT 2007 > PAGE 15 2007 accounts Operating result operating performance (in €m excl. VAT) BETTER OPERATING PERFORMANCE Gross operating surplus 20 47,26 An analysis of BRGM operating performance in the last four years shows steady growth in the first three years and an atypical result in the fourth. Operating performance increased from +¤0.32 million in 2004 to +¤0.73 million in 2006 and +¤6.55 million in 2007, while gross operating surplus increased by +¤0.47 million from 2004 to 2006 (¤4.19 million to ¤4.66 million), reaching ¤10.4 million in 2007. In a context of very high growth (+51.6%) in our international activities, this exceptionally wide variation is due in particular to the completion of a ¤2 million contract in Guinea (including renewal of a reserve made up when FY 2006 accounts were closed, due to the troubles that arose in that country in early 2007). Adding to the result was a delay in committing various external expenses, towards the end of the year when growth accelerated strongly. Finally, a high priority was given to production in 2007, in particular to comply with contract and project completion terms. However, the high rate of production is unlikely to be maintained in 2008, given the level of staff recruitment (new recruits are not immediately fully operational), the need for strengthened supervision arising from higher activity levels, renewed efforts to improve our quality management (integrated ISO 9001 management package, to be upgraded to 14001) and the decision to strengthen our contribution to committees whose work is relevant to our activities at European, national and regional levels. 10.4 16 12 8 6.55 4.67 4.19 3.77 4 0.32 0.56 0.73 0 2004 2005 2006 2007 +51.6% in international turnover > INTERNATIONAL TURNOVER BY REGION > Albania > Belgium > Estonia > Hungary > Malta > Algeria > Morocco > Tunisia > Netherlands > Romania > Slovenia > Switzerland > Turkey > UK > Arabia > Iran > Oman > Cambodia > China > India > Tajikistan > Brazil > Peru > Dom.

A great many areas rely on geological information , including natural risks, geothermal energy and deep storage of natural gas, CO2 and wastes. Geological knowledge is built up from continuously updated information collected from naturalists’ observations and from physical measurements, and also draws on fundamental scientific research. All this information is compiled into databases that can be accessed by citizens, public authorities and businesses. The BRGM is organising full compatibility between all its data through the interoperability rules currently being defined at international level. We create three-dimensional geological maps and models that represent our geological environment. In 2007, we continued the surveys and harmonisation between départements required to complete the 1:50 000 geological map of France. With our partners (universities, research institutions and SMEs), we guarantee the quality of current knowledge on France’s geology. We transfer our know-how abroad under different institutional support programmes, with a current focus on Africa. In the future, we will be moving from conventional geological maps to 3D blocks of customised geological information - a new and highly motivating challenge for the BRGM’s geologists and their partners! “ Geology strives to understand our Earth’s past while anticipating how it will evolve in the future. ” Catherine Truffert Head of the Geology Department 1 2 3 1_The 1:50 000 geological reference map of France. © BRGM Thickness in meters 2_State of progress in 1:50 000 geological reference mapping of all French départements. © BRGM 3_Mapping in Africa: geological map of Madagascar showing the six sheets to 1:100 000. © BRGM 4_Regolite studies: mapping the thickness of flinty Cretaceous alterites in the Paris Basin. © BRGM - F.

In partnership with Sander Geophysics and the Council For Geoscience: 21 460 km of magnetism and spectral radiometry recorded by helicopter and about 283 643 km by plane, used to draw up geological maps and define strategic zones for geochemical prospecting. Our planet is just over 4.5 > French Guiana The GéOyapock Project Mantle rock studies Geological and physico-chemical knowledge on mantle rocks (regolite) is essential in fields concerned with water resources, risk prevention, mineral raw materials, planning and low-temperature geothermal energy. Studies addressing a wide range of disciplines (geology, geophysics, geochemistry, geochronology and so on) are undertaken in collaboration with universities and public institutions under coordinated multidisciplinary projects. The International Year of Planet Earth Participation in preparations for the International Year of Planet Earth (officially launched at UNESCO on 12 and 13 February 2008). This geological mapping project undertaken with Brazils’ geological survey institute (CPRM) has produced the first transboundary geological map of Brazil and Guyana, to the scale of 1:250,000. The project analysed and interpreted the results of joint sampling missions on either side of the border, drawing on the scientific and technical skills of each partner. billion years old +13% In turnover for the Geology Department, 2006 – 2007 > Hérault Geological interpretation of walking trails The Hérault district council (Conseil Général) had decided to provide walkers with readily understandable information to help people get to know the main features of the area’s geology. In order to cover the very wide variety of rock types and landscapes found along the “green route” (the council’s network of walking trails), the BRGM helped to produce brochures interpreting the area’s geological heritage. €15.56m Turnover for the Geology Department, or 13.82% of total BRGM turnover in 2007 BRGM > AN NUAL REPORT 2007 > PAGE 21 GEOLOGY Flagship project 2007 “ Seismic studies were considered for many years as the exclusive preserve of the oil industry, but have now become a basic tool for geologists. ” Olivier Serrano Sedimentologist SEISMIC STUDIES HAVE OPENED UP TREMENDOUS PROSPECTS FOR GEOLOGICAL RESEARCH The BRGM has been involved for some ten years in a programme aiming to validate the borehole samples making up the subsoils databank (BSS).The goal is to produce isovalue (depth) maps of outstanding interfaces (between tiers or formations) in sedimentary basins. However, most of the data in the BSS cover layers that are relatively close to the surface, at a depth of 0 to 200 m on average, but there is increasing demand for data on much lower depths. The BRGM has therefore turned towards seismic research, which is opening up entirely new prospects for geological knowledge. Seismic studies are by no means a recent discipline: petroleum companies have all used them for prospecting in sedimentary basins. Since the Second World War, prospecting companies have recorded some 350 000 km of seismic profiles across France.The raw data (field recordings and documents) can now be freely accessed, as the Mining Code stipulates that they must be made public after 10 years. The BRGM has seized this opportunity to create data products from some of this information, thereby clearly showing the value of these data for improving knowledge on these basins. 2700 km of seismic profiles for the Paris Basin Some 1800 km of seismic profiles from the Aquitaine Basin have already been reprocessed and assembled into 14 regional transects, in collaboration with the French Petroleum Institute (IFP), and the geological interpretations incorporated into the geometric model of the basin. For the Paris Basin, 14 regional transects covering a total of 2700 km of seismic profiles have also been reprocessed and interpreted, and similar projects are under way for the South-East Basin, Alsace and Lorraine. The Office for hydrocarbon prospecting and production (BEPH), working under the Directorate-General for Energy and Raw Materials, has approached the BRGM to handle all raw seismic data on France and to make them available to users. To date, under an agreement with the BEPH, the BRGM is already managing some 30% of these data, and is planning to gradually collect and archive the remaining 70% (held by petroleum companies). The objective is threefold: to preserve the data, to make them available to potential users and to incorporate them into added-value data products such as updated 3D geological models. Opening up new horizons Our work in this area has already demonstrated the key role of seismic studies in furthering knowledge on the geology of regional basins (architecture, structural complexity, etc.).

In Europe, this is the responsibility of each State, not of the EU, but a need is emerging for a policy to meet common needs. Metallogenesis has been a research area at the BRGM for many years and is of particular relevance in this context. 2007 saw a significant increase in demand in this field, from institutions and companies in France and abroad (especially those involved in North-South cooperation programmes), resulting in numerous contracts with governments (often with international funding), operators and downstream industries (automobiles and aeronautics in particular). Given this context, we are pursuing activities that call on our core skills, such as metallogenesis (formation of mineral, aggregate and metal deposits) and deposit location and description. In parallel, demand for our post-mining expertise, now required for mining projects, is also on the increase. Our ambition is to help to build up, along with our colleagues from other geological survey institutes in Europe and worldwide, a global view of our planet’s mineral resources. “ Industrialists are commissioning BRGM studies to help them secure their mineral raw material supplies for the next 10 to 20 years.

By the end of 2007, the Europe-wide GIS contained data on 11 107 deposits and indicators, requiring a great deal of homogenisation. Securing supplies for the future Managing Europe’s mineral resources has become a major challenge, given increasing demand from Asia and fast-growing domestic consumption in China, with demand from Brazil, Russia and India also expected to rise significantly. Securing supplies for both European and developing countries has become a matter of priority. The need for sustainability means that all socio-economic and environmental impacts have to be taken into account. Where are Europe’s mineral resources located?

All these questions can be addressed thanks to the GIS, which has been produced to a scale of 1:1 500,000. The GIS on mineral resources in Europe covers some 5.5 million km2 and 44 countries (in full or in part), as far as Russian Karelia and Western Anatolia. Deposits are described in an associated database through over 40 search fields that provide information on location, typology, morphology and mineralogy, as well as on mineralisation age, weathering, the age and nature of enclosing rock, production, reserves and resources by type of mineral substance, and so on. Merging digital synopses to create a Europe wide GIS This GIS was developed by merging several digital synopses produced at the BRGM over the last few years, which provided the initial framework. These synopses were the GIS for Central and South-East Europe, developed for metallogenesis and environmental applications (under GEODE, the international Geodynamics and Ore Deposit Evolution programme), the French mining GIS (SIG Mines, for metal-bearing ores in France) and the GIS for Karelia, developed by the Franco-Russian metallogenesis laboratory to improve knowledge on the magmatic, structural Cuivre C and geodynamic control of “giant” ore deposits and their distribution over space and time.

The goal in France is to achieve a 20% share of renewables in total energy consumption by 2020. In the construction sector, where the potential is greatest in mainland France, deep and shallow geothermal energy offers a range of heating solutions and could cover 4% of all heating needs in buildings by that date. In the French overseas areas (DOM), where high-temperature geothermal energy is being used for electricity production, an even more ambitious aim is to cover more than 25% of energy demand at competitive prices. The BRGM is working on all these fronts. We have launched an integrated programme on shallow geothermal energy, with an experimental platform on geothermal heat pumps to be launched in 2008. On the deep geothermal energy front (1500 - 2000 m), geoscientific studies are continuing along with support to new borehole programmes in the Paris Basin aiming to supply further heat networks. In the DOM, our development activities at the Bouillante field in Guadeloupe are also moving ahead. Finally, our large-scale research programme on very high temperature geothermal energy at Soultz (Alsace) will be producing the first kWh of electrical power in 2008. To support the development of all forms of geothermal energy, whether to address climate change or the increasing costs of fossil resources, this area of BRGM know-how, which we have been building for over 30 years, is also available to third countries through international programmes. “ Geothermal energy will be making a major contribution to the objectives of the Grenelle Environment Forum.

AN EXPERIMENTAL PLATFORM FOR HEAT PUMPS One obstacle to the distribution of some types of geothermal energy is cost. This is true of shallow systems, which rely on heat pumps. The experimental platform at Orleans, which the BRGM decided to establish in 2007, will be investigating ways of improving the performance of subterranean heat exchangers while reducing costs, including underground installation costs. The new platform is being developed as part of the European geothermal centre, which involves the BRGM and the Centre Region authority through the State-Region Project Contract (CPER) signed on 8 March 2007 by the President of the Regional Council and the Prefect for the Centre Region. ” Hervé Lesueur Engineer, Head of Energy studies Assessing long-term impacts The platform will be used as a facility for tests, under realistic conditions, on subterranean exchangers of all types, including those already available on the market as well as innovative designs (as regards their geometry in particular). Experimental designs will be tested over several months and connected to loops simulating energy demand from a building. In parallel, data collected by partners from a network of instruments in different sites will be centralised and incorporated to be run through digital models. Crucial issues include the impacts of these exchangers on the subterranean environment. For example, if heat is taken from the subsoil, its temperature will obviously drop. Therefore: - Under what conditions will its temperature returned to normal? This is a matter of the dimensioning of the installation design, which directly affects its cost. We therefore need to have a better understanding of the relationship between design and the installation’s impacts on soil temperature, in order to optimise costs without damaging the subsoil. During the heating period, a vertical predesigned exchanger captures about 50 W per metre. - What would be the impacts of this in the long term? The aim here is to assess these over a long enough period that includes summer and winter seasons. A reference centre Reconnaissance operations. © BRGM im@gé BRGM > AN NUAL REPORT 2007 > PAGE 30 Another issue is to assess how far the geochemical, hydrogeological and biological equilibrium might be disturbed. What would be the long-term impacts of causing the soil to warm up and cool down during each operating cycle? This could slightly alter soil mechanics, which in turn would affect performance. This is the reason why, in parallel with our research work, we are also running support activities for the sector through training sessions and good practice dissemination. We are also contributing to the establishment of a regulatory framework with the relevant ministries. All these activities are conducted through various partnerships, in the Centre Region to begin with. The platform could also become a reference centre for subterranean heat exchangers, under the SIMBIO project now under development.

For example, we are involved in five new ANR projects, as coordinating agency for two of these, and in numerous European partnerships. We have continued to give priority to safety issues arising from storage in deep aquifers. At national level, we are also contributing to the project launched by Total (Lacq) in 2007, which is investigating CO2 storage possibilities in depleted natural gas reservoirs. We are also taking part in activities aiming to foster other demonstrator projects. In parallel, under the Centre Region’s Project Contract with State (CPER), the BRGM will be coordinating a preliminary study on CO2 storage in a deep aquifer near Artenay (Loiret département), downstream from a planned second-generation biofuel production plant. Engineering studies are conducted by Geogreen, a joint company established in 2007 by Geostock, the IFP and the BRGM. All these activities are supported by public information campaigns on this new technology for reducing greenhouse gas emissions. Geological CO2 storage allows cleaner fossil fuel combustion, and in the case of biofuel combustion, the emissions balance is negative – in order words, it helps to clean up the atmosphere. “ Time is getting short - sites selected for CO2 storage must be operational by 2020.

MODELLING CO2 STORAGE IN AQUIFERS The BRGM has been working for some 15 years on issues arising from underground CO2 storage, especially in deep aquifers. Potential storage aquifers, containing briny waters that are unfit for use, are located at depths of 800 m to 2500 m. The initial aim was to test the feasibility of storing CO2 in this way, using models as well as data from pilot sites (such as Sleipner, offshore from Norway).The current objective is to acquire the more detailed knowledge required to establish safety criteria. Defining safety criteria One of the issues is injection, the first stage in the storage process. All previous studies showed that it is the injection stage that triggers the strongest mechanical, chemical, hydraulic, thermal and other reactions. One important outcome in 2007 was a description of the three main change phases in the zone closest to the injection borehole. During the first phase, the aquifer remains in its initial state where the porous environment is saturated with water. In the second phase, the CO2 injected combines with the briny water, acidifying the surrounding environment. Phase 3 is when the CO2 tends ” Pascal Audigane Hydromodelling specialist to fill all the rock pores, depending on how long and how fast the gas is injected (within several dozen years at a flow rate of several million tonnes per year).The process is then known as “dewatering”. Specific studies are needed to predict the chemical effects of acidification and dewatering (mineral dissolution/precipitation) as well as mechanical effects, which may influence injection capacities and the leakproof properties of the storage reservoir. These studies are being conducted for a potential storage site in the Paris Basin, with a theoretical rate of injection of 1 million tonnes a year for 20 years. We are also looking into problems arising from the heterogeneous nature of the environment in which CO2 is injected. Up to now, most models were developed for homogeneous environments. However, geological and chemical heterogeneity must be investigated to ensure that simulations of spatial migration and geochemical interactions are based on sound data. All these activities are geared to the definition of safety criteria. One of these concerns injection pressure: if this is too high, the rock may fracture. Another criteria relates to the behaviour of the CO2 once it is injected into the aquifer. The issue here is to predict the spatial distribution of CO2 in the aquifer in the short term (10 to 20 years) and then in the next 1000 years. A third topic relates to the risk of fissures appearing or reappearing in the cap rock, which would allow the gas to leak out. Developing proposals for the Framework Directive Digital simulation of a CO2 bubble rising through a clayey reservoir interbedded with clay lentils. Structural heterogeneity plays a key role in the migration of stored CO2. © BRGM Im@gé BRGM > AN NUAL REPORT 2007 > PAGE 34 One of our objectives is to provide the government with expert advice for the preparation of the French proposals for the European Framework Directive on greenhouse gas storage. Our expertise in this area is recognised at the national and European levels. For example, the BRGM was recently entrusted with the management of the European CO2Geo2Net network of excellence.

We have now reached the most important phase in the implementation of these directives, involving the development of measurement programmes for each basin and action plans comprising initiatives to achieve and protect the required standards of water quality. The BRGM is closely involved in the entire process, providing support to the relevant water agencies and authorities. In parallel, we are continuing our research on diffuse pollution and its mechanisms, on the characterisation of natural and human pollutants, on complex systems (such as karsts), and on the socio-economic aspects of water management (cost-benefit analyses of different policies). As well as contributing to European programmes, we are working with emerging countries such as China, India and Brazil to seek alternative resources, and with Saudi Arabia to develop sustainable management approaches. As climate changes take hold, groundwater resources can only increase in importance, and this is what we are preparing for with our partners. “ In Europe, we first need to restore water quality, while in the countries of the South, the overriding aim is to preserve the quantities of water required to lessen the impacts of drought. ” Didier Pennequin Head of the Water Department 1 2 1_Regional information systems on groundwater: a synoptic map of potential groundwater reserves in Martinique.

DIFFUSE POLLUTION: THE COUNTDOWN Under the WFD, all member states must prove, by 2015, that the quality of water bodies covered by their action plans (officially, implementation by the end of 2009) is effectively up to the required standard. Diffuse pollution, particularly from farming (nitrates, pesticides, etc.), is of major concern. The mechanisms of pollutant transfer in soils and subsoils must be fully understood in order to model and predict their behaviour and define appropriate measures. The BRGM has been actively working on these issues for some 15 years, producing a number of proposals on methodology and analysis techniques (isotope analyses in particular), while also working to identify new water resources. Nitrate pollution - a major problem Among its activities at European scale, the BRGM has produced an extensive description of phytosanitary product use in farming, with an assessment of the environmental risk in each type of environment. The study involves 15 partners in nine countries working Pesticides Laurence Chéry Hydrogeochemist ” under the European FOOTPRINT project, which is coordinated by the BRGM. The results are being incorporated into easy-to-use software packages with which users can make approximate assessments of pesticide transfers to water bodies at any geographical scale (European, national, catchment basins and individual farms). These tools are already helping decision-makers to set priorities. The next stages will involve acquiring more detailed knowledge (transfer patterns in space and time, risks of water table contamination, etc.).This is the aim of the European AQUATERRA project, in which the BRGM is also involved. Concerning methodology, the BRGM is using new tracers to improve measurements of the rate of subterranean transfers of pollutants in fertilisers and phytosanitary products. For example, halogenated compounds (CFC-11, CFC-12 and CFC-113) and sulphur hexafluorides (SF6) were used in 2007 to date underground waters in different hydrogeological contexts, including volcanic systems in Martinique, fissured bedrock aquifers in Brittany and sedimentary formations in the Loire-Brittany and Ile-de-France regions. Nitrates are a major issue. BRGM studies in this area are focusing on the processes involved in natural denitration, to obtain more accurate quality assessments of underground and surface waters in catchment basins and identify more appropriate sites for drinking water abstraction according to their natural denitration potential. For example, a deep drilling campaign in 2007 identified naturally denitrated water resources in the subsoil in Brittany.

These have continued to grow through 2007, and now cover virtually all of mainland France, with the (temporary) exception of Alsace, Lorraine and Franche-Comté. The DPSM’s activities concern all former mining sites, whatever the substances mined, for which the State has had to take over responsibility. They cover issues such as safety for people and property, quantitative and qualitative water management and monitoring of soil stability and gas releases. The DPSM has also conducted safety engineering work to fill in galleries and mine shafts in derelict iron mines in Normandy, and sulphur mines in Marseille, for example. The department also manages intermediate technical archives formerly held by mine operators, mainly in the public sector, converting them into digital form to ensure ready access to all records in the event of an emergency. For all these activities, the department calls on the expertise of former public-sector mine operators, mainly Charbonnages de France. By the end of 2008, with the establishment of the fourth territorial post-mine unit (UTAM) for Eastern France at Freyming Merlebach, the DPSM’s activities will cover all of mainland France. “ Post-mine management is one of the phases of sustainable development and planning in former mining areas.

Decades of coal mining inevitably left their mark on the landscape, which is still pitted with hollows that formed as soils subsided, obstructing natural water flow. Successive mine operators, and finally Charbonnages de France, set up dewatering plants to restore water flow. The BRGM is now responsible, on behalf of the state, for ensuring the continued operation of these facilities. This is one of the missions entrusted to the UTAM-Nord at Billy-Montigny (Pas-de-Calais). These hydraulic safety facilities are essential to the safety of populations and housing in the coal basin, as they help to prevent flood risks.Two of the 54 existing facilities were handed over to local authorities in 2007, so that the BRGM is responsible for the remaining 52. The facilities are designed to operate according to highly specific criteria: for example, they cannot be left idle for more than eight hours at a stretch. 24-hour surveillance The BRGM subcontracts technical maintenance to specialised companies. At present, three of these cover the main sectors of the coal basin around Valenciennes, Douai and Lens-Bruay. Sites are monitored continuously for 24 hours a day, with staff on call in the event of a breakdown, due to pump failure, vandalism or electricity outages for example. The largest facilities typically run seven pumps, with a nominal output per station of up to 10 000 m3/h. The total volume of water pumped in 2007 amounted to just over 100 million m3, with annual variability obviously directly correlated to rainfall.The safety record is excellent as no breakdown exceeding eight hours was recorded. The Territorial Post-Mining Unit for the Nord département is responsible for operating hydraulic safety installations and water pumping stations in particular. © CHARBONNAGES DE FRANCE – ANMT BRGM > AN NUAL REPORT 2007 > PAGE 42 1 3 4 2 1_Oignies is the oldest coal mine in the Nord-Pas-de-Calais region. © CHARBONNAGES DE FRANCE – ANMT – 1990 2_The Petit Diable water pumping plant at Onnaing in northern France. © CHARBONNAGES DE FRANCE – ANMT 3_Subsidence at the Saint-Pierre-Bis station near Thivencelle, northern France. © CHARBONNAGES DE FRANCE – ANMT 4_The station at Waziers pumps out 10 000 m3 of water per hour. © CHARBONNAGES DE FRANCE – ANMT 2, 3, 4_The Nord-Pas-de-Calais region’s 54 operational water pumping stations restore surface water flow in areas where derelict mine workings have caused subsidence. 100 million m3 of water pumped from the Nord-Pas-de-Calais coal basin in 2007 BRGM > AN NUAL REPORT 2007 > PAGE 43 The Al Hoceima earthquake, 24 February 2004 (Morocco). © BRGM im@gé - H.

Climate risks are now compounding or magnifying the effects of geological hazards such as earthquakes. There are two strategic lines of action: risk reduction and adaptation. From the scientific point of view, this requires multidisciplinary and multi-risk studies to improve our knowledge on risks to the safety of certain sites that arise from land movements, coastal erosion and seismic activity. The BRGM has gained widely recognised expertise in all these aspects, both in France and abroad, and is now responsible for managing and/or coordinating a large number of national and European projects. In practice, we implement innovative evaluation methods designed to gradually incorporate risk-sensitive socioeconomic parameters into our models. To address the transboundary - and sometimes global - scale of certain risks, we are also contributing to numerous international projects, particularly with the countries of the South. “ To address the combined effects of geological and climate hazards, multi-risk analyses have become essential.

ASSESSING VULNERABILITY TO ANTICIPATE RISKS Vulnerability is a determining factor of risk, whether due to natural or human causes. What degree of damage to industrial zones, towns of villages can be expected in the event or an earthquake or volcanic eruption? Anticipating risks and adequate planning measures (for buildings, road networks, etc.) depends on finding answers to this question.Vulnerability analyses are used to translate a given hazard level into an estimated degree of risk. The concept of physical vulnerability to seismic risks is fairly well understood today, and our emphasis today is on vulnerability to other risks. The vulnerability concept is usually addressed from four different angles. Physical vulnerability concerns structural damage (to buildings and infrastructure) on the scale of a given territory. Systemic or functional vulnerability relates to the links between urban or regional systems and economic and social systems. Social vulnerability encompasses the vulnerability of populations, organisations and institutions. Finally, economic vulnerability concerns both microeconomic damage (to local production facilities for example) and macro-economic damage (market impacts for example). Up to now, BRGM studies have mainly focused on physical and systemic vulnerability. Sri Lanka: simulation of the maximum height of the tsunami above sea level. © BRGM BRGM > AN NUAL REPORT 2007 > PAGE 46 ” Evelyne Foerster Engineer in soil dynamics, civil engineering and digital modelling From land movements to tsunamis This is the case with land movement risks, which we investigated under the European LESSLOSS project, completed in 2007, using a pilot site in Italy. In the late 1990s, the municipality of Corniglio (Parma Province) sustained severe damage from a landslip. An inventory of the damage was carried out, as well as an assessment of physical vulnerability to differential settling of the ground within a given zone.This produced fragility contours, which highlight the probability of damage according to the intensity of a phenomenon. Contour maps of this kind will be used to build scenarios for other risk-prone regions. Different kinds of natural risks arise from tsunamis.The Sri Lanka project is working to develop a methodology for assessing vulnerability to tsunami risks, based on data from the tsunami that swept across South-East Asia in late 2004. A great many observation missions have been carried out in the south-east of Sri Lanka in order to draw up an inventory of damage and conduct surveys among the population. Again, the resulting data we used to produce fragility contours. A similar approach is being used under the ANR’s recently launched VULSACO project to test the vulnerability of sandy beaches to climate change effects and human pressures. Also of note are developments in our approach to multi-risk analysis, for example in an assessment, on behalf of the World Bank, of vulnerability in Algiers to several different risks including earthquakes, land movements and flooding. In parallel, we have also begun assessments of socioeconomic vulnerability, for example under the European ENSURE project which the BRGM is coordinating. The VULNERISK project, launched by the BRGM in 2006, is modelling losses according to the intensity of a given phenomenon and the scale of damage. Ultimately, the aim is to integrate all aspects of vulnerability within an overall approach. 1 3 2 the 2ndlargest share of compensation paid out by the French natural disasters fund (CatNat) was for damage caused by clay soil swelling and shrinkage 5 4 1_Tsunami wave propagation at -25, -110, -230 and -250 mn (Sri Lanka 2004). © BRGM Im@gé 2_Major lateral displacement caused by soil liquefaction (Mexico 1985). © BRGM Im@gé 3_Damage along Sri Lanka’s coasts caused by the December 2004 tsunami. © Photo GSMB 4_Digital model of the landslide at Corniglio (Italy): comparison between computed and observed displacement (from 04/07/96 to 04/11/96). © Source: BRGM et Studio Geotecnico Italiano, S.r.l. 5_Soil liquefaction causes buildings to lean over (Nigata, Japan 1964). © Steinbrugge Collection, NISEE BRGM > AN NUAL REPORT 2007 > PAGE 47 A holding tank for acid waters from a sulphur mine. © BRGM im@gé - D.

Savings are needed in fossil fuel use, because reserves are becoming depleted, because prices are rising, but especially to reduce greenhouse gas emissions. Savings are also needed in the consumption of mineral raw materials, largely for the same reasons. And the volume of waste also has to be reduced to prevent harm to the environment.The BRGM is closely involved in all these areas through national European and international programmes. Recycling - a threefold challenge In response to the European Union's goal of achieving what the Commission has called a “recycling society,” the BRGM has proposed a range of tools, including for decision support. For example, we are coordinating the FORWAST project (6th FPRD, which has a twofold aim: one is to draw up an inventory of materials stocks that have accumulated within the 27 member countries of the EU, with a forecast of the quantities of waste to be anticipated, by resource category, in the next 25 years; the other is to assess the environmental impacts of different scenarios (prevention, recycling and waste treatment). Generally speaking, recycling raises issues that fall into three main categories. One is the recovery of secondary resources, which requires waste sorting techniques. Another is environmental characterisation and evaluation. The third is the reduction of CO2 emissions. The BRGM is working actively on all three fronts. For example, we are building on our long-established know-how in mineral separation techniques to separate the components of different wastes and produce purified fractions, either for use as alternatives to primary resources or for environmental protection purposes. At our dedicated facility in Orléans, we are looking in particular into electrical and electronic equipment recycling and the treatment of low-dosage pollution in soils and sediments. The LIMULE2 project (on multi-scale lixiviation), cofinanced by the ADEME, is investigating the behaviour of residues degraded by meteoric waters (moisture precipitated from the atmosphere), to further understanding of their environmental impacts. Development and frugal resource use Finally, the BRGM is taking an increasing interest in synergies between waste recycling and CO2 emission reductions. For example, we are coordinating the ANR’s DECALCO project, which is aiming to improve the environmental performance of the Solvay process for producing sodium carbonate: the CO2 released is used to stabilise hyperalcaline briny residues into carbonates that can then be recycled. Recycling is set to become one of the foundations of an economic system that will need to reconcile development and frugal resource use, an approach to which the BRGM is already actively contributing.

Our priorities in the area of metrology are to identify and quantify the mineral and organic micropollutants found in groundwaters and the components of soils and subsoils. Our primary aim is to supply geological data for internal needs, such as isotope dating of geological formations, and data to support environmental protection. We also provide supporting documentation for public policy development, which has to be based on reliable knowledge and data on mineral and organic substances that are potentially dangerous to people or the environment. Finally, we conduct research and development work to design innovative analytical tools that help to understand pollutant transfers and to trace them back to their sources. We are involved in a great many national and European projects and contribute actively to the AQUAREF virtual laboratory. This was established in mid-2007 in order to exchange and pool the analytical expertise of five public institutions to support implementation of the Water Framework Directive. At the same time, we are seeking innovative solutions to address future challenges such as new and lowdosage polluting substances. “ Data quality for analytical purposes requires highly sophisticated methodologies, techniques and expert knowledge. ” Gilles Hervouët Head of the Metrology, Monitoring and Analysis department 1 2 1_Herbicide migration: taking on-line measurements during percolation through a soil column. © BRGM im@gé 2_Infra-trace metals: quadripolar ICPMS instrument with collision-reaction unit. © BRGM im@gé 3_Geothermal potential in Tahiti: iron-bearing carbonated springs in the Leiefaatautau valley. © BRGM im@gé 4_Water resource management in Mayotte: a hillside reservoir near Dzoumogné. © BRGM im@gé 3 4 Highlights 2007 Zircon dating Successful implementation of the U-Pb isotope dating method using zircons to date the deposition of quaternary volcanites (coupled laser ICP/MS-MC).

NANOMATERIALS TO CLEAN UP POLLUTION Layered double hydroxides (LDH) make up a family of materials that was first discovered in the 19th century and which could be used to trap substances such as nitrates, arsenic or CO2. LDHs are among the very few known anion exchangers among mineral species. When chemically broken down into amorphous oxides, they are capable of reforming, so that they can be used repeatedly. They are rare in the natural world, but can now be chemically synthesised into LDHs using a non-toxic process. A low-cost depollution method The chemical composition of LDHs, which are generically written as [M(II)1-xM(III)x(OH)2] [An-]x/n.mH2O, can be highly varied. For example, M(II) will be a divalent cation such as Mg2+, Mn2+, Zn2+, Co2+, Cd2+, Cu2+, Ni2+ and so on, while M(III) is a trivalent cation such as Al3+, Fe3+, Cr3+ or Ga3. The interfoliar anions (An) that give structures their ” Fabian Delorme Materials Physics and Chemistry specialist stability are as likely to be Cl- chloride anions as fragments of ADN. Typically, unwanted anions are trapped either by reconstructing mixed oxides or by substituting much less toxic interfoliar anions (An-) that are then released into the environment. A method for synthesising LDHs from common industrial minerals and/or certain industrial wastes was developed in 2004 for large-scale production at much lower cost than with previous techniques (SYNTHDL project). The process also results in microto nano-particles whose composition is suitable for the target applications. One of these applications is water depollution. Studies carried out in 2005 showed that LDHs can completely purify water with arsenic concentrations similar to those found in Bangladesh (six times higher than the maximum levels set by the WHO). A project financed by the Centre Region (TRAINIT), involving the BRGM and the University of Orléans Institute of Earth Sciences (ISTO), starting in 2008, will be looking into the potential of LDHs for eliminating nitrate pollution from water tables in the Beauce cereal-growing region. From feasibility to optimisation Another potential application is CO2 capture, more specifically in its anionic form (CO32- carbonates). The BRGM has developed an innovative process under the ANR’s CAPCO2 project, in partnership with the French Petroleum Institute (IFP), several university laboratories and CNRS research teams and companies such as Lafarge, Gaz de France and Arcelor. Preliminary results show that the capturing potential of LDHs is similar to that of amines, with much lower environmental toxicity. Having demonstrated the technical feasibility of the process, the project is now working to optimise energy consumption for LDH regeneration, to ensure that the process can become economically viable.

We have therefore adopted a proactive strategy for transposing the European INSPIRE Directive (adopted in April 2007), aiming to apply its founding concepts in France and to explain the issues, principles and rules involved to local authorities. The INSPIRE Directive is designed to guarantee the interoperability of environmental data, whatever their source. This has guided our work in developing a new version of the InfoTerre portal, which provides access to georeferenced information produced by the BRGM and other organisations and to a wide range of online services. The number of searches through our web sites continued to grow in 2007, with the environment and natural resources featuring as the main concerns. To cater more effectively for user needs, we have decided to implement an “intelligent” search engine that will simplify data searches and improve access, including for non-specialists, to the dozens of databases run by the BRGM. All these dimensions, from semantics to “intelligent” classification and cross-searching, are to be continued and upscaled. “ Environmental information is more than ever a core requirement for policy development. ” Jean-Marc Trouillard Head of the Information Systems and Technology Department 1 2 1_Environmental mapping: http://carmen.ecologie.gouv.fr/ 2_Enhanced reality techniques are used to combine actual observations with virtual models. 3_The Géocatalogue: version 2 came on line in late 2007, with improved search functions. 4_The “Sensor web” concept, an integrated system through which sensors transmit their position, link up to the internet and record metadata for remote reading. © 2006 Open Geospatial consortium, Inc.

Groundwaters: the ADES website The ADES was entirely renovated in 2007 to offer more user-friendly access and new downloading features (http://ades.eaufrance.fr). All cartographic information is now interoperable and access to high-quality data is provided through online services that are compatible with the water information system (SIE). Information systems INFORMATION SYSTEMS Digitised public reports Public reports produced by the BRGM have been digitised and the full text can now be accessed on the BRGM web site. 7883 reports are already available for downloading free of charge. The Géocatalogue Version 2 of the Géocatalogue (a catalogue and search engine available from the national Géoportail) came on line in late 2007, with improved search functions provided by a new “intelligent” search engine developed by Exalead. On-line sensor data Under a research project on new information technologies, tests were made on new interoperability standards for sensor data and online access. A prototype is now providing access to real-time data on water levels from several piezometric sensors.

INFOTERRE: INFORMATION AT THE CLICK OF A MOUSE The first version of the InfoTerre portal went on line in 1998. Our objective was to make all geoscientific information produced by the BRGM available to all potential users (decision-makers, geologists, engineering consultancies, etc.) through the internet. The basic idea was to present information in map form, with digitised maps gradually phasing out traditional maps in printed form. The new version completed at the end of 2007 enhances the functions of InfoTerre as a gateway to information (http://infoterre.brgm.fr), thanks to the implementation of interoperability standards and the exclusive use of Open Source applications. What does InfoTerre contain? Suppose a decision has been made to develop a given locality in mainland or overseas France. Decisionmakers can connect to InfoTerre to access all the geoscientific information they need for the zone in question, including groundwater resources, their depth, their geological structure, the location ” Pierre Lagarde Information Systems Engineer of existing boreholes and their characteristics, as well as any natural risks to which the area might be subject (land movements, clay soil shrinking and swelling, seismic risks, etc.) and contaminated soils and sites. Interoperability, ergonomics… The ergonomics of new version of the portal have been entirely redesigned (web 2.0) to rely exclusively on the Open Geospatial Consortium (OGC) interoperability standards. The aim is to be able to display information from very different sources with just a few mouse-clicks, including data outside the BRGM’s spheres of activity. One example is the data produced by the CEMAGREF on avalanche risks, which can be displayed on InfoTerre and coupled if need be with our own data on land movement risks. Users can therefore access information from other geoscientific data producers without the need to transfer them first to the BRGM website. We also make every effort to comply as closely as possible with applicable standards under the European INSPIRE Directive, which came into force in May 2007. …and efficiency In parallel, we are pursuing our technological work to improve efficiency, given that the applications and interfaces handled by the portal require very large computing capacities. Concerning content, we are also continuing efforts to post information from the different BRGM departments on line (including reports, catalogue entries, map legends and so on), after a very demanding validation phase. Finally, on the key factor of ergonomics, information needs to be accessed as rapidly as possible and we are therefore working to develop harmonised semiological bases that will meet the need for maximum efficiency in user-friendly operation. InfoTerre allows the consultation of digital geological maps. © BRGM BRGM > AN NUAL REPORT 2007 > PAGE 58 1 Tools to prepare ones own map (composition and location, …). 2 2 1000 3 visits each day to the Info Terre site 1_The Infoterre 2007 interface. 2_Metadata help to visualise and understand data by describing each data layer and how it is represented. 3_Searching for and accessing data: in this example, relevant data is associated with the drilling operation selected.

Serrano significant increase in graduate recruits from Group A engineering schools, although most of our scientific staff is obviously recruited at PhD level, with geology, hydrogeology and geotechnology predominating. Our recruitment in 2007 has enabled us adjust the distribution of our staff between different topic areas, by defining profiles that match the BRGM’s changing needs. Training also leverages development, and we slightly exceeded our training scheme objectives in 2007. Encouraging mobility Finally, in-house mobility is also helping to adapt our areas of expertise to the current issues we need to address, and is strongly encouraged. A marked upward trend in 2007 is likely to continue through 2008.

Inter-disciplinary integration In late 2007, the AFAQ-AFNOR Certification Agency renewed the BRGM’s ISO 9001:2000 certification for all its activities and premises for a period of three years. We had first obtained certification in December 2004. Thanks to our customer-geared policy, we have been able to define clear targets at all levels of BRGM organisation. These have resulted in responses that are more closely matched to both in-house and external demands and expectations. At a time of rapid growth in our activities, the “process approach” is effectively removing divisions between disciplines and helping all staff members to develop an overall, practical view of their individual activities. The result is greater satisfaction among customers and partners, at central government and local levels, companies and research institutes and also at European and internaOur approach tional levels (cooperation has successfully and development assisimplemented quality tance organisations). improvement Our new management as a dynamic system has promoted betprocess. ter handling of mechanisms such as calls for tenders from public administrations, companies and agencies, and more effective fulfilment of StateRegion project contracts, Carnot projects and international projects. Towards ISO 14001 certification Our policy for continuous improvement is opening up the BRGM to new and more ambitious goals, for example on environmental issues in the wake of recommendations from the Grenelle Environment Forum. We constantly try to anticipate social needs, and this is why we are now considering an ISO 14001 certification procedure. The “sustainable development” commission set up in 2007 within the BRGM works council reflects the determination of the BRGM and its staff to work in practical ways towards rational management approaches to the major issues of the 21st century. “ ” Florence Auclaire Quality Manager BRGM > AN NUAL REPORT 2007 > PAGE 62 The four cycles of quality assurance (planning - doing - acting - checking) are implemented continuously. TRAINING TRAINING PROGRAMMES IN ALL OF THE BRGM’S TOPIC AREAS Over and above our research, public service and international cooperation activities, we make every effort to transfer BRGM knowledge and know-how to others. Trainee numbers up by 40% in 2007. © BRGM im@gé Particular emphasis was given in 2007 to training in two topic areas, water and contaminated lands and waste. Examples were the training sessions on the new regulations and methodological developments in the area of contaminated soils and sites. These sessions were organised in close collaboration with the Ministry for Ecology, Energy, Sustainable Development and Planning. The BRGM has effectively become a reference institution for technical training in these areas. Our training programmes also cover all our other topic areas, albeit to a lesser extent. On natural risks, for example, training modules on offer address not only seismic risks, but also risks arising from land movements and clay soil swelling and shrinkage. We also offer courses on mineral resources as well as pioneering modules for the geothermal and geological storage sectors. Our training programmes are designed to cater for very different levels of knowledge, and range from introductory courses to highly specialised technical modules. Trainee numbers are on the increase Most of the BRGM’s training activities are in continuing vocational training, with courses designed for a very broad audience including government services, public institutions, local authorities, engineering consultancies and industries. Customers from different organisations increased by 64% in 2007 (from 98 to just over 160), while the number of course participants increased by 40%. Training sessions are organised into inter-organisation courses, inhouse (custom designed) courses and combined 56 training sessions organised in 2007, up by 14% sessions attended by BRGM agents on in-house training schemes and external customers. Partnerships for training The BRGM is also involved in initial training, in partnership with academic institutions or in response to individual requests from its staff, many of whom are in regular demand from universities and higher education establishments (grandes écoles). 2007 also saw the introduction of a new system of co-produced training programmes, with the ADEME on geothermal heat pumps, for example, with the INERIS and the School of Higher Laurent Albouy Head of Training Programmes Studies on Public Health (EHESP) in Rennes on chronic health risks arising from contaminated sites and soils, and with the Rennes Agrocampus on soil science applications to indiThe BRGM has become vidual sewerage systems. a reference establishment At the BRGM, we believe for technical training in water that training is one of our issues and contaminated fundamental missions - in environments. other words, transferring knowledge and know-how to all those involved in the geosciences and, more generally, in sustainable development issues. “ ” BRGM > AN NUAL REPORT 2007 > PAGE 63 The BRGM Group SUBSIDIARIES AND HOLDINGS The BRGM’s subsidiaries and holdings are grouped into three holding companies, SAGEOS (engineering and geothermal energy), SERGAP (instrumentation) and BRGM SA (residual BRGM holdings in the mining sector).

This upturn stems from the feasibility studies carried out for the renovation of existing facilities, and from new projects. The high-energy division is continuing its programme of exploratory drilling in La Réunion, preparing for the reconnaissance of the northern part of the Bouillante reservoir with a new drilling programme and pursuing the examination of a project for Dominique, which is hoping to export its surplus power to Guadeloupe and Martinique. A new operating contract for the Bouillante plant in Guadeloupe was implemented in 2007. Studies on the behaviour of facilities have begun, focusing on fluid reinjection as a priority. Internationally, CFG Services is running projects in China, Kazakhstan, Spain and the Azores. Finally, 2007 saw the completion of studies on a device for field measurements of biocorrosion in steel piping for fluid transport. Marketing is expected to begin in the next few months. 1 Géothermie Bouillante SA Géothermie Bouillante specialises in the development of power supplies from geothermal energy in Guadeloupe and the Caribbean region as a whole. > Chairman: Didier Houssin Géothermie Bouillante runs the only power plant in Guadeloupe’s Basse-Terre area and contributed almost 8% of the island’s electricity supplies in 2007. > EDEV holding (EDF group): 40% Power production in 2006 did not achieve cruising speed until the summer (industrial commissioning of the B2 facility in July); on 1 January 2007 , the Operations and Maintenance contract came into force, whereby GB handed over plant operations and maintenance to CFG Services for a period of ten years, with binding obligations as to results. Production from the B1 facility in 2007 was 18.2 GWh, and 76.8 GWh from B2, amounting to a service availability rate, expressed in operating time, of 84% (compared to 30% in 2006) and 91% (86% in 2006) respectively. These excellent results confirm that plant operation is now largely stable. After two years of simultaneous operation of the B1 and B2 facilities, the anticipated reduction in well-head pressure caused a reduction in the flow of geothermal fluid, justifying financing commitments in 2007 for two studies, to be concluded in 2008, on: > Managing Director: Francois Le Lann > Turnover: ¤10.4m > SAGEOS holding (BRGM Group): 60% > Payroll: operations are contracted out to CFG Services, with 11 employees on site and support from experts at the Orleans head office • Modelling of the operations of the geothermal reservoir and feasibility of reinjection of the geothermal fluids currently released into the sea; • Possibilities for installing a binary-cycle plant running on residual fluids, which would eventually replace the B1 facility now nearing the end of its useful life (after operating since 1985). An application was submitted to the energy control commission (Commission de régulation de l’énergie - CRE) to increase the sale price per kWh produced by the B2 facility from 82 ¤/MWh to 100 ¤/MWh as from 1 November 2006. After numerous exchanges, a favourable decision from the CRE was notified on 28 January 2008 to the EDF and the BRGM. The new contract has been submitted for signature. Since the new sale price took effect from 1 November 2006, total income for GB for FY 2007 has reached about ¤10.4m (compared to ¤6.2m in 2006), producing an operating surplus of ¤0.765m.

Operating surplus amounted to 1.89 M?. Net after-tax profit increased by 44% over FY 2006 at ¤1.29m, more than 20% of turnover. A dividend is to be paid out to shareholders for FY 2006, for the sixth year running. Growth continued in all markets for the company’s products. Electrical equipment for exploratory environmental and geotechnology studies accounted for over half of all product sales. Most of this product range involves electrical imaging systems, for which SYSCAL Pro Switch multi-electrode and multi-channel measuring equipment is best suited thanks to its high measurement yields. Induced polarisation equipment, used for mineral prospecting, accounted for about one quarter of sales. Sales in this range have been growing steadily for seven years, mainly to the traditional Canadian market, but 2007 also saw large sales volumes in China and Mongolia. Four PMR instruments (proton magnetic resonance) used for groundwater prospecting were delivered to France, Jordan, Uganda and Rwanda. Almost 85% of turnover was from exports, especially to Europe and Asia/Oceania. For the first time, sales volumes in Africa overtook those to the Americas. The largest sales were to France, Russia, Canada, Australia and the United States. In the R&D field, the industrial prototype of the PROMIS frequential electro-magnetic profiling apparatus was made available to customers for full-scale testing. This instrument is designed for use in environmental and mineral prospecting, to detect lateral facies variations and fault zones. Marketing operations will begin in Canada, where the technique is most frequently used. Development studies began on a multi-sensor magnetic resonance instrument for groundwater prospecting, supported by a far-field reference technique that improves measurement quality in noisy environments. This new instrument is expected to attract new customers for products of this type.
