ConocoPhillips Announces 2005 Reserve Replacement of 230 Percent ; Reserve Replacement of 100 Percent, Excluding Sales and Acquisitions

Business Wire, Feb 21, 2006

HOUSTON -- ConocoPhillips (NYSE:COP) today announced preliminary net additions of 1.553 billion barrels of oil equivalent (BOE), including Libya and equity affiliates, to its proved reserves during 2005. The company's reserve replacement ratio was 230 percent, based on 675 million BOE of production, bringing ConocoPhillips' total reserves to 9.4 billion BOE. Excluding sales and acquisitions, such as increases in LUKOIL ownership and re-entry into Libya, ConocoPhillips' reserve replacement ratio was 100 percent.

The above excludes 0.3 billion barrels associated with the company's Canadian Syncrude operations. U.S. Securities and Exchange Commission (SEC) regulations define the company's Syncrude operations as mining related; therefore, these operations are not reported as part of the company's conventional oil and gas proved reserves. Also, consistent with SEC guidelines to use year-end prices for reserve estimates, proved oil reserves for the Surmont project in Canada were not included.

Total reserve additions, including revisions, improved recovery, purchases, and extensions and discoveries, were 1.569 billion BOE. Costs incurred, as defined by Statement of Financial Accounting Standards No. 69 (SFAS No. 69), are expected to be $10.508 billion. This includes ConocoPhillips' estimate of LUKOIL's 2005 year-end results. At the end of 2005, ConocoPhillips had a 16.1 percent equity interest in LUKOIL. Estimated reserve additions and costs incurred related to LUKOIL were 0.655 billion BOE and $2.511 billion, respectively.

"The improvement in 2005 from 2004 is attributable to extensions and discoveries from our legacy projects in Qatar, the United States and the Asia Pacific region, as well as our re-entry into Libya and our increased equity ownership in LUKOIL," said Bill Berry, executive vice president of Exploration and Production. "We remain committed to replacing reserves at competitive finding and development costs."

Pro Forma Information

The company's pro forma reserve replacement rate averaged 155 percent for the past five years. Excluding the impact of the company's investment in LUKOIL, the five-year average reserve replacement was 109 percent of production.

To provide meaningful, prior-period comparisons, the company is providing the following pro forma operating information. This pro forma information was prepared by combining the historical results of Conoco and Phillips for all reporting periods presented prior to the merger and those of ConocoPhillips since the merger, including the company's investment in LUKOIL.

CONOCOPHILLIPS' RESERVES ESTIMATION FOR EQUITY INVESTMENT IN LUKOIL

ConocoPhillips' estimated year-end 2005 reserves related to its equity investment in LUKOIL are based on LUKOIL's year-end 2004 reserves (adjusted for known additions, license extensions, dispositions and public information) and include adjustments to conform to ConocoPhillips' reserves policy and provide for estimated 2005 production. Any differences between this estimate and actual reserve computations will be recorded in a subsequent period.

EXPLANATION OF RATIOS

The reserve replacement ratio of 230 percent was calculated by dividing the sum of changes to estimated proved crude oil, natural gas and natural gas liquids reserves from revisions, improved recovery, purchases, extensions and discoveries, and sales during 2005 by production of 675 million BOE. The reserve replacement ratio of 100 percent was calculated by dividing the sum of the 2005 changes noted above, excluding purchases and sales, by the 2005 production.
