BP FILES FORM 20-F WITH US SECURITIES AND EXCHANGE COMMISSION

BP's 2003 Form 20-F, filed with the US Securities and Exchange Commission (SEC) in Washington, D.C. late yesterday, shows total proved reserves reported under SEC requirements are 23 million barrels more than those presented in its 2003 Annual Report and Accounts to Shareholders issued in March.

BP's 2003 Form 20-F - which reconciles its financial accounts, published under UK Generally Accepted Accounting Practice (GAAP), with US Generally Accepted Accounting Principles - reports proved reserves of 18.361 billion barrels of oil equivalent, compared with 18.338 billion barrels in its 2003 Annual Report and Accounts.

BP said that it considers the 23 million barrel difference, which represents some 0.1 per cent of its total proved reserve base, including equity accounted entities, to be immaterial.

As a UK-registered company reporting under UK GAAP, BP determines its proved reserves under the UK Statement of Recommended Practice, Accounting for Oil and Gas Exploration, Development, Production and Decommissioning Activities (SORP).  In estimating reserves, it uses long-term planning prices to determine the commercial viability of upstream resources. For 2003 these prices were $16 a barrel for oil and $2.70 per thousand cubic feet for natural gas.

In contrast, SEC guidelines require the use of year-end market prices which, as of December 31, 2003, were $30.10 a barrel for Brent crude and $5.76 per thousand cubic feet for Henry Hub gas.

Using year-end prices and assuming they apply to the end-of-field life has the effect of increasing the volumes of oil and gas likely to be recovered economically from reservoirs, thus adding to proved reserves. On the other hand, using year-end prices has the effect of decreasing reserves in the case of production-sharing agreements (PSAs) where a higher oil price results in lower volume entitlement.

BP said that use of year-end pricing and some changes in the way it applies SEC interpretations of SEC regulations relating to field fuel gas and the use of technology in determining reserves, while giving rise to larger variations on a regional basis in its proved reserves, accounted for the upward difference of only 23 million barrels on an aggregate basis between its 20-F and UK SORP estimates.

The company believes that its long-term planning price assumptions provide the most appropriate basis for estimating oil and gas reserves and will continue to use this basis for its UK reporting.

The company said it had received comments from the SEC on its 20-F Filing for 2002 and that the SEC review process was still ongoing.
