DALLAS –Kosmos Energy’s (NYSE: KOS) Tortue-1 exploration well in block C8 offshore Mauritania has encountered additional hydrocarbons while drilling to total depth to evaluate the deeper Albian stratigraphy.

Based on the preliminary results, Tortue-1 has intersected approximately 10 m (32 ft) of net natural gas pay in the lower Albian section. This is in addition to the previously announced 107 m (351 ft) of net pay encountered in the Cenomanian, which was the primary objective. The well was drilled beyond the primary objective to obtain deeper stratigraphic information and to enable seismic calibration of the Albian, which will be tested in subsequent wells.

Located 285 km (177 mi) southwest of Nouakchott in 2,700 m (8,858 ft) of water, and drilled with theAtwood Achieverdrillship, the Tortue-1 well was drilled at a total cost of approximately $125 million to a TD of 5,100 m (16,732 ft).

The Tortue discovery area has also been renamed Ahmeyim. Kosmos currently owns a 90% interest in the Ahmeyim discovery, along with Societe Mauritanienne Des Hydrocarbures et de Patrimoine Minier (SMHPM) at 10%.
