1. RUSSIAN OIL AND GAS RESERVES Ray Leonard YUKOS Uppsala, May 22, 2001

2. Factors to consider • Existing Reserves • Production Capability • Export Capability • Future Discoveries

14. EXPLORATION MATURITY

15. Potential of Russian Shelf • Seven major basins, each equal to or larger than the Gulf of Mexico or the North Sea • Extensions of producing trends in Pechora Sea, Kara Sea and Sea of Okhotsk • Thick sedimentary basins with all elements for hydrocarbon accumulations in other Arctic and Pacific Basins

17. CONCLUSIONS • Russian oil reserves are probably in the range of 90-105 Billion barrels • These reserves will be capable of sustaining an additional 35% increase over current levels (7.5 MMBOD) for an extended period • New export oil and gas pipelines will allow additional Caspian oil to be marketed and supply Russian oil and gas to the Far East • A combination of mature, developing and frontier exploration can add an estimated 40-50 billion barrels and larger amounts of natural gas • Russian and Caspian oil exports will reach the level of one half of the Middle East by 2010 • Russian gas reserves allow a significant increase from current production and will assume increasing importance as world production eventually peaks and begins to decline
