Kosmos Energy said Monday that its Teranga-1 exploration well has made a “significant gas discovery” in offshore Senegal.
The Teranga-1 well was drilled to a total depth of 14,714 feet and encountered 31 meters, or 102 feet, of net gas pay in “good quality” reservoir in the Lower Cenomanian objective.
Kosmos said the results confirm a “prolific inboard gas fairway” that extends about 124 feet from the Marsouin-1 well in Mauritania through the Greater Tortue area on the maritime boundary to the Teranga-1 well in Senegal.
Teranga-1 is located in the Cayar Offshore Profond block, about 40 miles northwest of Dakar in about 5,905 feet of water.
Kosmos has now drilled five consecutive successful exploration and appraisal wells in the fairway with a 100 percent success rate.
During the process, the company has discovered a gross Pmean resource of about 25 trillion cubic feet and estimates the fairway may hold more than 50 trillion cubic feet of 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 Energy chairman and CEO Andrew G. Inglis.
Kosmos holds a 60 percent interest in the Teranga-1 well.
Timis Corporation Limited holds a 30 percent stake and Société des Pétroles du Sénégal (Petrosen) holds a 10 percent stake.
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.
