Exploration and production company Kosmos Energy today that its Teranga-1 exploration well offshore Senegal has made a significant gas discovery.

The Teranga-1 well was drilled to a total depth of 4,485 meters. The well, located in the Cayar Offshore Profond block approximately 65 kilometers northwest of Dakar in nearly 1,800 meters of water, encountered 31 meters (102 feet) of net gas pay in good quality reservoir in the Lower Cenomanian objective.

Kosmos says that well results confirm that a prolific inboard gas fairway extends approximately 200 kilometers from the Marsouin-1 well in Mauritania through the Greater Tortue area on the maritime boundary to the Teranga-1 well in Senegal.

According to Kosmos, the company has now drilled five consecutive successful exploration and appraisal wells in this fairway with a 100 percent success rate. In the process, the company has discovered a gross Pmean resource of approximately 25 Tcf and estimates the fairway may hold more than 50 Tcf of resource potential.

Andrew G. Inglis, chairman and chief executive officer, said: “Our continuing exploration success demonstrates we have opened a super-major 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.”
