Kosmos Energy’s Teranga-1 exploration well offshore Senegal has hit significant gas pay.

Located in the Cayar Offshore Profond Block in nearly 1,800 m of water, the Teranga-1 well was drilled to a total depth of 4,485 m. The well encountered 31 m of net gas pay in good quality reservoir in the Lower Cenomanian objective.

Kosmos said well results confirm that a prolific inboard gas fairway extends about 200 km from the Marsouin-1 well in Mauritania through the Greater Tortue area on the maritime boundary to the Teranga-1 well in Senegal. Kosmos has now drilled five consecutive successful exploration and appraisal wells in this fairway with a 100% success rate.

The company has discovered a gross mean resource of about 0.7 Tcm and estimates the fairway might hold more than 1.4 Tcm of resource potential.

Andrew G. Inglis, chairman and CEO, said, “Our continuing exploration success demonstrates we have opened a supermajor scale basin offshore Mauritania and Senegal with world-class resource potential. Given the scale and quality of the gas resource discovered along the inboard trend, our focus is to move this resource through to development. Our forward exploration plan is to mature the two independent tests with oil potential in northern Mauritania and in the outboard of Mauritania and Senegal for drilling in 2017.”

Kosmos holds a 60% interest in the Teranga-1 well, along with Timis Corp. (30%), and the Société des Pétroles du Sénégal (Petrosen), which has 10%.

Since 2014, Kosmos has held rights to conduct exploration in the St. Louis Offshore Profond and Cayar Offshore Profond license areas under production sharing contracts with the Government of Senegal.
