10 10 Russian Strategic Motivators 1.Respect / National Pride 2.National Security 3.Economic Recoverability

11 11 Reserve Life Index Reserve Life Index = Proved Reserves Production Rate For Russia: Reserve Life Index = 23 on oil production Reserve Life Index = 74 on natural gas For Western Companies: Reserve Life Index = 11

12 12 Economic Recoverability

16 16 Russian Oil & Gas Reserves 1.Russia has been and will continue to be a strategic resource to world economies. 2.How do Russian authorities define petroleum reserves? 3.How do their definitions compare with the West (SPE and SEC)?

17 17 Russian approach to reserve classification recognizes the natural progression of resource identification, delineation and conversion to reserves. Resources and reserves are classified by where a reservoir, field, or region is located within this sequence of events.

18 18 Russian Reserves Classifications

19 19 Comparison of Russian Reserve Definitions With Western Standards

20 20 Russian Federation Classification Scheme

21 21 Russian & Western Classification of Reserves Russia West (SPE, SEC) Technical recoverability Commercial recoverability Key Criteria Geophysical and geological exploration completed Proved by exploration and production operations Commercially viable Geophysical and geological exploration completed Proved by drilling Projected commercial viability Geophysical & geological exploration completed Minimum drilling data available Paper estimates are partially proven Assumed to be existent based on presence of favorable data, structures and analogs Geological and engineering (or production) data available to fully prove commercial viability of development 1) Studies not fully completed, namely: Well explored producing adjacent areas Unexplored areas analog to explored properties Commercially viable in existing economic and technological environment Assumed to be existent in: Unexplored areas based on analog data from similar fields Assumed to be commercially viable in existing economic and technological environment 1) SPE and SEC classification of proved reserves slightly differs as SEC proven reserve requirements are more stringent (offset rule) resulting in more conservative estimates АВС 1 + С2D ProvedProbablePossible ProvedPossible 30% С 1 70% С1 Probable

22 22 Russian Oil & Gas Reserves Conclusions 1.Russia will continue to be a major energy supplier in the globalization of world economies. 2.Russian authorities define petroleum reserves as best illustrated using the McKelvey Box. 3.Russia is a strong competitor and formidable adversary with abundant supply of natural resources and a talented, educated work force.
