Drilling Report

BowLeven Plc 19 February 2007 Bowleven plc: Well drilling update Bowleven plc announces it has now completed drilling and logging operations on the IE-2 well located in Block MHLP 7 of the Etinde Permit in Cameroon. The well, which was drilled to appraise the IE-1 discovery made by Total in 1981, reached a depth of 8675 feet subsea. Based on petrophysical log evaluation, two hydrocarbon bearing zones have been identified. The upper zone, located in the Biafra formation at a depth of approximately 3310 feet, comprises approximately 50 feet of net pay in good quality gas bearing sandstone. The gas is believed to be relatively dry with few associated gas liquids. The lower zone is located in the Isongo formation at a depth of 7850 feet. It comprises approximately 130 feet of net pay in good quality sandstone and is believed to contain both gas and condensate. A drill stem test is planned over this lower interval and a further update will be issued shortly.
