conventional and unconventional oil and gas
Vladimir Vysotsky, VNIIZARUBEZHGEOLOGIA (JSC) CONVENTIONAL AND UNCONVENTIONAL OIL AND GAS: RESOURCES AND INFLUENCE ON THE WORLD MARKET Источник: et al, 2012 More than 500 oil and gas basins with a total area of 118 million sq km have been recognized. HC fields have been discovered in 240 basins. The Northern hemisphere harbors 93% world oil and 94% world gas resources. Twelve major oil and gas basins account for 70% world oil and 60% world gas resources. Deepwater basins (> 500 m) account for 6.4% world oil and 6.0% world gas resources. 1 World conventional and tight oil resources, billion tons Conventional oil* Remaining reserves Tight oil** Cumulative production 566 Remaining reserves Cumulative production 47 Неоткрытые ресурсы Undiscovered resources Initial Reserves/ ultimate resources ratio – 64% Cumulative production/ultimate resources ratio – 30% Oil recovery factor – 30% (* estimated by VZG as of 1.1.2013 ) Undiscovered resources Initial Reserves/ ultimate resources ratio – 1.9% Cumulative production/ultimate resources ratio - <1% Oil recoveryy factor – 5% (** estimated by IEA, 2013) 2 CONVENTIONAL AND TIGHT OIL POTENTIAL (remaining reserves and undiscovered resources) CONVENTIONAL OIL (countries with conventional oil potential > >55 billion tons) tons) TIGHT OIL (countries with tight oil potential > >1 1 billion tons) tons) billion tons 11 10 2 10,2 10 9 7,9 8 7 6 5 4,4 3,7 4 35 3,5 3 1,2 1,2 1,1 Pakistan Canada Indonesia 1,8 2 1 Thirteen countries account for 81% of world total oil potential including 75% of its unexplored resources (VNIIZarubezhgeologia VNIIZarubezhgeologia,, 2013) Venezuela Libya Argentina China US Russia 0 Ten countries account for 78% of world oil potential (IEA, 2013) 3 2000--2012 US TIGHT OIL PRODUCTION HISTORY 2000 MMt/yr 100 (K2) (D3-C1) 90 70 60 50 (P2) Tight oil p plays 80 2012 – 94.3 MMt (29 5% off US ttotal (29.5% t l oil il production) d ti ) (P1) (N1) Shale Revolution-2 (D3) (K2) 40 (P1) 30 (K2) 20 10 Projections: 2015 – 180 (45%), 2020 – 260 (59%), 2025 – 330 (69%), 2030 – 380 (72%) Source: IEA, 03.2013 4 World conventional and shale gas resources, trillion m3 Conventional gas * Cumulative production Undiscovered resources 703 Remaining reserves Initial Reserves/ ultimate resources ratio, % - 46.8 Cumulative production/ultimate resources ratio, % - 17.6 Gas recovery factor – 80% * Estimated by VNIIZarubezhgeologia, VNIIZarubezhgeologia 2013 Shale gas ** Remainingg reserves Cumulative production 207 Undiscovered resources Initial Reserves/ ultimate resources ratio, % - 2.4 Cumulative production/ultimate resources ratio, % - 0.5 Gas recovery factor – 25%** ** Estimated by IEA IEA, 2013 5 CONVENTIONAL AND SHALE GAS POTENTIAL resources)) (remaining reserves and undiscovered resources CONVENTIONAL GAS (countries with conventional gas potential >10 >10 trillion m3 Ten countries account for 62. 62.5% of world total gas potential, Including 72. 72.2% of its unexplored resources (VNIIZarubezhgeologia VNIIZarubezhgeologia,, 2013 2013)) SHALE GAS (countries with shale gas potential >5 >5 3 trillion m ) Ten countries account for 79. 79.1% of world total shale gas potential (IEA, 2013) 6 2000-2012 US SHALE GAS PRODUCTION HISTORY Bm3/yr 290 240 190 Shale gas plays 2012 production – 250 billion m3 (37% of US total saleable gas production) (D3-C1) (K2) (D2) Other plays (J3) 140 (D3) (C3) 90 40 Marcellus Shale Revolution -1 Haynesville (C2) (D3) Barnett Forecast: 2015 – 300 (43%); 2020 – 350 (46%); 2025 – 380 (46%); 2030 – 400 (45%) Source: IEA, 03.2013 7 WORLD UNCONVENTIONAL (OTHER THAN TIGHT OIL AND SHALE GAS) OIL AND GAS RESOURCES OIL, billion tons GAS, trillion cubic meters* Heavy and Extra Heavy Oil Oil Sand Coal-Bed Methane Gas in lowpermeability reservoirs (Tight Gas) Oil shale*** * VNIGRI, 1989 ** OGR, 6, 2012 *** Oil Shale Sh l D Deposits i off the h W World, ld 1988 * As reported by VNIIGAZ-GAZPROM, 2012, 2013 Gas Hydrates – 10 000 trillion m3 (VNIIGAZ – GAZPROM) 8 WORLD OIL PRODUCTION FORECAST Production, mln.t 5400 Growth - 1,2% 5200 1,0% 5000 0,8% Total Oil Production (Conventional and Unconventional Oil) 4800 4600 Growth - 1,2% 43.7 4400 C Conventional ti l Oil Production P d ti 1,0% 43.4 4200 0,8% 43.1 4000 3800 2010 43.1 2015 2020 2025 2030 Cummulative production/ultimate resources ratio, % Oil Production Growth: 1970-1990 p.a. – 1,9%; 1991-2010 p.a. – 1,4% Scenarios: 2011-2030 p.a.: 0,8% (BP), 1,0% (EIA), 1,2% (LUKOIL) 9 OIL AND GAS FIELDS DISCOVERED IN 2012 Number of discoveries and field sizes Largest oil and gas discoveries Reserves Countryy Basin name Field name Sea depth, p , m Oil Oil, MMt Gas, Gas Bm3 Angola Kwanza Cameia 1675 205 42.0 Mozambique Ruvuma Golfinho 1027 - 524.0 Mozambique Ruvuma Coral 2260 - 226.0 Mozambique Ruvuma Atum 1000 - 184.

AMU DARYA BASIN Minara Yashlar Eloten Osman South Galkynysh gas field (Reserves 21-26 trln. m3) 22 CONCLUSIONS Hydrocarbon production from unconventional sources in volumes sufficient for the essential redistribution of world export–import flows is only possible in countries with extremely large unconventional hydrocarbon resources and with, mature oil and gas sector (large rig fleet) and favorable natural conditions (large freshwater resources). These requirements are met in the US, China, and Russia. US (shale gas resources – 18.8 trillion m3, tight oil resources – 7.9 billion tons; rig fleet – >1800 rigs.) Gas production growth rate suggests that domestic consumption will be satisfied and gas exports may start by 2020. Export potential is estimated at 35 billion m3 by 2025 and 75 billion m3, by 2030. 2030 Tight oil production will grow up to 380 MMt by 2030 and provide a possibility to reduce oil imports from 421 MMt in 2012 to 130 MMt in 2030. Oil can be supplied from Canada, whose export potential by 2030 is estimated at 145 MMt. China (shale gas resources – 26-31 trillion m3, tight oil resources – 4.4 billion tons, rig fleet – 1500 rigs.) N ti l shale National h l gas resource development d l t program envisages i shale h l gas production d ti att 80 billion billi m3 (23% off th the country’s t ’ total t t l gas 3 production) in 2020 and 150 billion m (27.3%), in 2030. Based on field development scenarios prepared by international agencies and ВР, 2030 shale gas production in China is estimated at 60-90 billion m3. In all probability, the country’s import requirements by 2030 will be ranging from 100–200 billion m3. Russia (shale gas resources – 8.0-9.5 8 0 9 5 trillion m3, tight oil resources – 10.2 billion tons, rig fleet – about 800 rigs.) Shale gas production is not planned because of the high conventional gas reserves to production ratio. Tight oil production from the Bazhenovskaya Formation is anticipated at 15–20 MMt by 2020 and 70 MMt, by 2030. Total oil production in 2030 is anticipated at 540-550 MMt (ВР Forecast, 2013.) Venezuela is likely to become world’s largest oil exporter mostly due to the development of extra heavy oil resources and supply about 260 MMt /yr oil to the market starting from 2020. By then, a significant increase in conventional oil production and exports, accordingly, is anticipated from Brazil and Iraq and conventional gas production and exports from Australia, Qatar and new participants (Mozambique, Tanzania). Excessive hydrocarbon supplies are highly probable on the p and,, especially, p y, Asia–Pacific markets. European Increased competition may reduce oil and, especially, gas prices. In all probability, oil prices may drop down to US$90/bbl, and spot gas prices, down to US$300/1000 m3. At the same time, oil prices are hardly likely to drop down below US$80/bbl, because many nonconventional oil production projects will become uneconomic in this case. 23
