Endeavour Announces Increase in Proved and Probable Reserves in 2010
HOUSTON, Feb. 24, 2011 -- Endeavour International Corporation today announces an increase in proved and probable reserves as of December 31, 2010 resulting in a 419 percent reserve replacement rate of 2010 production, based on 2P reserves.
"Even with the sale of our Cygnus North Sea asset, we continue to grow the company's reserves strongly through the drill bit," said William L. Transier, chairman, chief executive officer and president. "Our 2010 successes are directly attributable to the efforts of our North Sea drilling and the development of our onshore US program, including a substantial enhancement to the value of Cygnus through appraisal drilling."
Proved and probable reserves at year-end 2010 increased to 43.7 million barrels of oil equivalent (mmboe) compared to 38.9 mmboe a year ago. Extensions, discoveries, sales and purchases added 6.3 mmboe during 2010. Production for the year was 1.5 mmboe.
The upward revisions in 2P reserves were the result of the appraisal welldrilled in West Rochelle Block 15/26b, the addition of reserves from theBacchus development and strong results from the Louisiana/Texas Haynesvilleprogram.

As of January 1, 2010, the Securities and Exchange Commission (SEC) changed its rules to permit oil and gas companies, in their filings with the SEC, to disclose not only proved reserves, but also probable reserves and possible reserves. Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible - from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations - prior to the time at which contracts providing the right to operate expire. Probable reserves include those additional reserves that a company believes are as likely as not to be recovered and possible reserves include those additional reserves that are less certain to be recovered than probable reserves. We use may use certain terms in our news releases, such as "reserve potential," that the SEC's guidelines strictly prohibit us from including in filings with the SEC. In addition, we do not represent that the probable or possible reserves described herein meet the recoverability thresholds established by the SEC in its new definitions. Investors are urged to also consider closely the disclosure in our filings with the SEC, available from our website at http://www.endeavourcorp.com. Endeavour is also subject to the requirements of the London Stock Exchange and considers the disclosures in this release to be appropriate and/or required under the guidelines of that exchange.
