PRESSURES AND OVERPRESSURE IN THE SUBSURFACE
3 – 5 November 2014 | Bali * 12 – 14 November 2014 | Bangkok * 17 – 19 November 2014 | Ho Chi Minh
Course objectives
The principal objective of the course is to teach participants how pressure data relate to the safe and efficient exploration and
exploitation of petroleum reservoirs. Overpressure is experienced in most sedimentary basins where reservoirs are associated
with fine-grained lithologies (such as shales), occurring at depths of 2.0km or greater below sea-bed.
Recent advances in the understanding of overpressure, in particular the magnitude of overpressure resulting from each of the
main mechanisms under realistic basin conditions, give improved confidence in estimating pore pressures. The course is presented
as a combination of Powerpoint based lectures and practical exercises.
By the end of this 3 day course, delegates will be able to:
 Be familiar with industry standard methods for establishing hydrostatic, lithostatic, fracture gradients and displaying
pressure data.
 Understand the origins of formation pressure data and how these data can be used to interpret fluid composition and fluid
contacts.
 Be familiar with the main mechanisms which lead to overpressure and to differentiate between primary and secondary
mechanisms.
 Understand which data types can be used to predict pressures in shale dominated sequences using industry standard
techniques, and the limitations of these techniques.
 Be aware of the effects of overpressure on the hydrocarbon system including, lateral transfer, lateral drainage,
hydrodynamics, seal integrity, reservoir quality, hydrocarbon migration and hydrocarbon maturation.
Who should attend?
This training course is designed for geologists, geophysicists, petrophysicists and reservoir/drilling engineers with an interest in
overpressure and high-pressure reservoirs, i.e. anyone who wants to understand over-pressure and to know about the tools to
predict it ahead of the bit. A familiarity with oilfield practices will be an advantage.

Expert Course Leader:
Don Basuki
Expert Course Leader:
Jakob Heller
Expert Course Leader:
Stephen O’ Connor
Currently Don is Ikon Science’s
Geopressure Manager for Asia
Pacific
region.
He
is
responsible
to
provide
technical
and
business
leadership in the field of
geopressure, to mentor and manage the
Asia Pacific regional Geopressure staff, to
lead the team in achieving high quality
technical support and lead project
management to exceed client’s objectives
and expectations, to provide mentoring and
training as required and to represent
company in the external meetings and
client communication.
Jakob is a strong industry
professional with training in
sedimentology and facies
modelling,
including
interpretation of sedimentary
facies from cores, well logs
and seismic data. Previously trained on
submarine fan plays offshore Nile Delta
and extensive work experience in Middle
Jurassic, Mid-Norway, Cretaceous of
Danish North Sea, Eocene, Miocene Gulf of
Suez, Cretaceous Western Desert of Egypt,
and the Triassic in Syria and Miocene of the
Nile Delta. He has an MSC in
Sedimentology/Geology
from
the
University of Copenhagen Denmark. His
Master’s thesis was undertaken in
collaboration with STATOIL Norway and
focussed on the sedimentation and
diagenesis of the Middle Jurassic Garn
Formation.
Stephen is responsible for
all technical aspects of Ikon
GeoPressure globally. He
oversees the entire lifecycle
of pressure prediction
projects
and
regional
pressure studies from concept to
completion. He is passionate about pore
pressure prediction and as such publishes
papers and regularly presents at
international conferences. Technically he
leads and mentors the GeoPressure team.
Jakob has 10 years working experience as a
geologist in Denmark, UK, Egypt and
Malaysia (KL) and has focussed on
integrating a variety of data types and
other information into a regional
interpretation of the subsurface. He has
extensive experience in creating pressure
databases, producing regional pressure
distribution maps, analysing hydrodynamic
systems, seal-breach risking studies,
fracture pressure algorithms, well plans
and log-based pressure prediction (E.g.
Equivalent Depth Method, Eaton and
Bowers) as well as real-time well
monitoring.
After graduating from Leeds University
with a BSc in Geological Sciences he
started his career working on exploration
assignments for Unocal and BP/Amoco
before returning to university to
undertake an MSc. in Sedimentology at
Reading University. His dissertation was
the study of the sedimentology and
diagenesis of the reservoir interval, Old
Red Sandstone Group, Well 206 8-7, Clair
Field, offshore Shetland. Following this he
worked for service companies on
sedimentology/diagenesis in areas such as
UKCS including the Atlantic Margin and the
Middle East before specialising in areas
such as pore pressure and fault seal.
Don has more than 17 years of industry
experience in several countries with various
roles. He has wide range of experience in
pore pressure and wellbore stability
modeling using petrophysical, drilling and
geophysical data along with extensive
wellsite experience throughout many
different geological environments such as
deepwater, extended reach drilling, HTHP
and in complex lithologies. He was
successfully involved in some of record
breaking projects, such as Poseidon (the
deepest well in Gulf of Mexico, 2001) and
Sakhalin-1 Chayvo (the longest well in the
world, 2008). Enhancing this experience,
Don is a certified OASIS Engineer in Pressure
Management and Performance Drilling.
Don graduated his Bachelor of Science in
Geology in 1994 from Wichita State
University, Wichita, Kansas, USA and
continued to undertake a Master of Science
degree in Geology from the same
university. He graduated his MS in 1997. He
was a recipient of various scholarships.
Stephen has over 20 years of experience
and his background as a petroleum
geologist has lead him to work with many
types of oilfield data, particularly in the
areas of reservoir quality, structural
geology with particular reference to
geomechanics, fault seal and pore
pressure.
Since joining Ikon Geopressure in 2010,
Jakob has worked on pore pressure
projects from the Central North Sea, Niger
Delta/offshore West African Margin and
extensively in the SE Asia region including
Australia, Vietnam, Thailand, Indonesia,
Malaysia/Borneo. The projects involved
well plans; seal breach studies and column
height assessments, hydrodynamic studies
and regional pressure studies.
