ITEM 7.01. Regulation FD Disclosure.

Attached as Exhibit 99.1, which is incorporated herein by reference, to this Current Report on Form 8-K is a copy of the Company’s press release dated March 5, 2008.

The Securities and Exchange Commission has generally permitted oil and gas companies, in their filings with the SEC, to disclose only proved reserves that a company has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions. We use the terms “probable,” “possible” and “non-proved” reserves, reserve “potential” or “upside” or other descriptions of volumes of reserves potentially recoverable through additional drilling or recovery techniques that the SEC’s guidelines may prohibit us from including in filings with the SEC. These estimates are by their nature more speculative than estimates of proved reserves and accordingly are subject to substantially greater risk of being actually realized by the company.

ITEM 9.01. Financial Statements and Exhibits.

Endeavour Announces Increase in Year-end Reserves for
2007 and Full-year Production

Houston, March 5, 2008 – Endeavour International Corporation (“Endeavour”) (AMEX:END) (LSE:ENDV) today announced that proved and probable reserves at year-end 2007 increased to 29.8 million barrels of oil equivalent (mmboe) compared to 29.6 mmboe a year ago (see Table 1). Extensions, discoveries and upward revisions to prior estimates added 3.5 mmboe, more than replacing production of 3.3 mmboe or approximately 9,000 boepd during 2007. The upward revisions in proved and probable reserves were a result of better-than-expected production from the Goldeneye, Brage and Njord fields and increased reserves in the Endeavour operated Rubie, Renee and Rochelle assets (R-blocks). The R-block reserves, which are covered under the existing Field Development Plans, will be developed for additional near-term production. Once development is complete, the R-blocks should add approximately 7,000 boepd of new production, net to Endeavour.

As a result of strong performance from producing assets and our acquisition of producing properties in the United Kingdom in 2006, sales volumes for 2007 increased dramatically from the prior year. For the full-year 2007 sales volumes of 3.3 mmboe or 9,000 boepd compared to full-year 2006 volumes of 1.0 mmboe or 2,800 boepd (see Table 2). Currently, year-to-date production has averaged approximately 10,000 boepd.

“The foundation of our producing asset base, acquired in three different transactions since late 2004, has continued to deliver production and reserve performance that has exceeded expectations. Of special note are the Goldeneye field, where production continues to outperform forecasts, and ongoing development programs in the Brage and Njord fields,” said William L. Transier, chairman, president and CEO. “Good internal technical work has identified new drilling opportunities and increased reserves, particularly in our operated R-blocks. The strong production results and the year-end reserve study confirm the depth and quality of our asset base and provide the foundation on which to confidently grow the company.”

¹ The volumes shown in this table represent volumes that were recorded as sales in the company’s records based on actual liftings of liquids    which was less than our actual physical production. Physical production for 2007 totaled 9,200 boepd.

The Securities and Exchange Commission (SEC) only permits oil and gas companies, in filings with the SEC, to disclose proved reserves that a company has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions. We use certain terms in this release, such as probable reserves and possible reserves, to describe volumes of reserves potentially recoverable through additional drilling or recovery techniques that the SEC guidelines strictly prohibit us from including in filings with the SEC and are non-GAAP measures. These estimates are

by their nature more speculative than estimates of proved reserves and accordingly are subject to substantially greater risk of being actually realized by Endeavour. Investors are urged to also consider closely the disclosure in our filings with the SEC, available from our website at 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.
