The Company’s current oil production is derived from Potanay, East Kamennoye and Paitykhskoye fields. The licenses for the Potanay and East Kamennoye fields are held by the Company’s subsidiary KMNGG. The license for the Salym field was held by KMNGG until relinquishment in 2000. The license for the Paitykhskoye field is held by the Company’s subsidiary Paitykh Oil.
For the year ended December 31, 2000, Potanay represented 84% and East Kamennoye represented 16% of the total production of the Company’s consolidated subsidiaries. For the first half of 2001, Potanay represented 83% and East Kamennoye represented 17% of the total production of the Company’s consolidated subsidiaries.
The Company’s East Kamennoye and Potanay fields currently produce using natural reservoir energy, with production enhanced where necessary by artificial lift methods, including beam pumps and electrical submersible pumps. Production from Chernogorskoye is supported by an extensive waterflood program.
The Company produces sweet (low sulphur content), light oil. Potanay and East Kamennoye have very low gas to oil ratios, and therefore produce relatively small volumes of gas. A portion of the associated gas from the Company’s operations is used for power
generation in the field. The remainder of the gas is flared in compliance with local requirements.
The Company is reducing its reliance on contracted services in the areas of drilling, workovers, procurement, construction and technical services. The Company has modified its own rigs to enable them to perform more efficiently and more reliably than had previously been available through the use of contracted rigs.
All of the Company’s fields are located in the Khanty Mansiysk region of western Siberia, one of the largest hydrocarbon basins in the world. This region covers about 1.3 million square miles east of the Ural Mountains in north central Russia. Major hydrocarbon reserve discoveries in the area began approximately 40 years ago and since that time, according to the Russian government, more than
50 billion barrels of oil have been produced from the basin's Cretaceous and Jurassic reservoirs.
As of June 30, 2001, the Company’s fields contained 57 wells that have been drilled since 1998 and 205 wells that were previously drilled predominantly by KMNGG during the time it was a Russian state exploration enterprise. Productive wells not currently producing are wells that have produced, but are awaiting work-over activity such as pump maintenance, recompletion or stimulation.
