Endeavour Tests Positive Flow Rate at Rochelle, Could Double Production

Endeavour has announced that drill stem testing of the Rochelle appraisal well 15/27-11 has achieved flow rates of 41 million cubic feet of gas per day and 2,300 barrels of oil condensate per day from a 72/64-inch fixed choke. This highly successful test confirms the commerciality of the undeveloped Rochelle discovery in Block 15/27 located in the United Kingdom sector of the North Sea.

The rates were achieved from a limited 20-foot interval at the top of the 77-foot net pay in the Lower Cretaceous Kopervik sandstone. Endeavour holds a 55.6 percent interest in the well and is operator for the block. Nexen Petroleum U.K. Limited is a joint venture participant and holds 44.4 percent interest.

"This is a major milestone in the growth of our company as the Rochelle field development has the potential to more than double our current production," said William L. Transier, chairman and chief executive officer. "The success of our first company-operated appraisal project reflects the quality of our technical evaluations and operational capabilities, and we intend to move quickly towards development. Our preliminary estimates indicate recoverable reserves in excess of 30 million gross barrels of oil equivalent."

The Rochelle 15/27-11 appraisal well was drilled to a total depth of 10,369 feet subsea approximately two kilometers northeast of the 15/27-9 discovery well drilled in 2000. Endeavour acquired the Rochelle area in 2006. It lies in the Outer Moray Firth in the prolific Kopervik sand fairway between the Goldeneye and Brodgar producing fields.
