19.02.2010 Reserves Audit

Reserves Audit  


OAO LUKOIL finished an evaluation and independent audit of its oil and gas reserves, as they stand on January 1, 2010.
The audit results by Miller and Lents, a US firm, suggest that the Company’s proved hydrocarbon reserves as of January 1, 2010 came to 17.5 billion barrels of oil equivalent, including 13.7 billion barrels of oil and 22.9 trillion cubic feet of gas.
The evaluation was performed in accordance with the US Securities and Exchange Commission (SEC) standards until the economic limit of commercial production is reached. The Company resolved to undergo reserves evaluation according to the SEC standards to provide better transparency and compatibility of its reserves data compared with that of its competitors.
The evaluation was performed with consideration of the changes in the field development plans approved by the Company’s Board of Directors on November 19, 2009 as part of the Company’s Strategic Development Program for 2010-2019.
In accordance with the SEC rules, there has to be an approved development plan as a requirement to book undeveloped reserves as proved. This plan must set the start of field operations within a five-year period, if there are no other factors that would explain a later commissioning. Considering the changes introduced into development plans and their commissioning dates, the Company transferred 1.8 billion barrels of oil equivalent from the category of proved reserves into lower reserve categories and into resources. The Company expects that these volumes will be returned into the proved reserves category as their development start date draws nearer or some new technologies are applied.
In 2009, proved reserves were extended due to geological exploration, production drilling and acquisitions, and totaled 782 million barrels of oil equivalent, which was 95% of the Company’s annual production volume. Of the 782 million barrels, geological exploration and production drilling accounted for 617 million barrels of oil equivalent, while acquisitions accounted for the remaining portion of 165 million barrels of oil equivalent.
The main 2009 acquisition was the buy-out of 46% of the equity interest in the LUKARCO B.V. joint venture. This joint venture owns 5% of the TengizChevroil joint venture which is developing the Tengiz and Korolevskoye fields in Kazakhstan. As a result of the transaction, the Company’s proved reserves increased by 102 million barrels of oil and 130 billion cubic feet of gas.
In summary, in terms of proved hydrocarbon reserves volume LUKOIL retains its leading positions among the Russian and international companies.
