Total final consumption (TFC) is energy consumption of all final consumers. Final losses (FL) – all losses includes losses in energy distribution, transmission and transport TFC = TPES – FL 24.11.2017 5 Total Primary Energy Supply (TPES) 14 000 13 647 Mtoe 12 000 10 000 ~ 5.3% per year 6 1018 000Mtoe 6 000 4 000 2 000 EIA.

Petroleum can range from solid to gas, but the term is generally used to refer to liquid crude oil” (Schlumberger Oilfield Glossary) Crude oil linear alkanes (CnH2n+2): n-pentane 30-50% iso-pentane cyclic alkanes (CnH2n): cyclopentane 25-75% arenes: benzene, toluene 10-20% sulfur and nitrogen compounds up to 5% o light oil (condensate): tboiling< 250 C heavy oil (tar, bitumen) 24.11.2017 13 Oil, natural gas, petroleum(2) Natural gas 95% methane + ethane + propane + butane, etc. Petroleum – a general term for all kinds of natural hydrocarbons 24.11.2017 14 Hydrocarbon resources distribution 24.11.2017 15 Oil resources distribution and production Russia 6.1% (12.7%) USA+Canada 2.9+10.2=13.1% (12.3+5= 17.3%) Iran 9.3%(4.6%) S.Arabia 15.6%(13.5%) Iraq 9%(4.4%) Kuwait 5.9%(3.7%) 240.7 / 4.32 = 56.8 years Venezuela 17.5%(3.3%) 8 countries – 76.5% proved reserves Total proved reserves (incl. oil sands) Production 240.7 billion tons (2016) 4.32 billion tons (2016) 24.11.2017 16 Oil consumption by countries 20% 12.4% 4.7% 3.5% 4.3% 24.11.2017 17 NG resources distribution and production Norway 1% (3.1%) USA+Canada Russia 17.8% (17.3%) 4.7+1.2=5.9% Turkmenistan 9.3%(2%) (20.7+4.8=25.5%) S.Arabia 4.5%(2.5%) Iran 18%(5.3%) Qatar 13%(4.6%) 186.6 / 3.52 = 52.5 years 8 countries – 69.5% proved reserves Production (2016) Total proved reserves (2016) 3.55 trillion cub. m per year 186.6 trillion cub. m (3.21 billion toe) 18 24.11.2017 Gas consumption by countries 22.7% 12% 5% 3.3% 5.4% 24.11.2017 19 Shale gas revolution?

These experts have predicted nine out of the last zero oil-reserve exhaustions.” Quote by C. Maurice and C. Smithson, Doomsday Mythology: 10,000 Years of Economic Crisis, Hoover Institution Press, Stanford, 1984. 24.11.2017 26 Traditional point of view 24.11.2017 27 Biotic hydrocarbons origin IV. Petroleum accumulation I. Sedimentation: remains Micro oil migrated upward of zooplankton had settled and was trapped within to a sea or lake bottom porous rocks (reservoirs) Micro oil generation: kerogen 1.5-2 km II. Diagenesis: organic matter mixed with silt and clay was was converted to micro oil buried under sediments 3-4 km III. Catagenesis: organic matter (OM) migrated downward (3-4 km). 0 6 km “Oil window” Thermodistruction (t>150 C, p=200-800 bar): OM was converted24.11.2017 to a waxy material Source rock 28 (kerogen) The end of petroleum era? You remember? Hydrocarbons for the next ~60 years only Is it True? 24.11.2017 29 Non-traditional point of view Concept of the abiogenic deep origin of hydrocarbons 24.11.2017 30 History The first rejection of the biotic hypothesis of petroleum origin was made by Alexander von Humboldt at the beginning of the nineteenth century. 24.11.2017 31 History Dmitry Mendeleev (1867) stated clearly that petroleum is a primordial material which has erupted from great depth through “deep faults” - weakness in the crust of the Earth via which petroleum would travel from the depths. 24.11.2017 32 History Marsellin Berthelot (1860th) demonstrated the generation of petroleum by dissolving steel in strong acid. He produced a suite of n-alkanes and made it plain that such were generated in total absence of any “biological” molecule or process. Later, Biasson and Sokolov observed similar phenomena and likewise concluded that petroleum was unconnected to biological matter. 24.11.2017 33 The XXth century Russian geologist Nikolai Kudryavtsev (1951) analyzed the geology of the Athabasca Tar (Alberta, Canada) and concluded that the most plausible explanation of accumulation of this huge deposit is abiotic deep petroleum. 24.11.2017 34 The XXth century Vladimir Porfiriev Petr Kropotkin Emmanuil Chekaluk Vladilen Krayushkin 24.11.2017 35 Abiogenic deep origin of hydrocarbons Mantle HC form oil and gas 0 km, 293 K, deposits 1 bar DF migrates into the Earth’s crust 50 km, 900K, 15 kbar Hydrocarbons are generated in the 200 km, 1700K, Earth’s upper mantle – deep fluid (DF) 70 kbar 24.11.2017 36 Could the synthesis of complex hydrocarbons out of inorganic systems under mantle conditions be demonstrated in a laboratory?
