Kosmos Energy’s Teranga-1 exploration well offshore Senegal has made a significant gas discovery, encountering 31 m (102 ft) of net gas pay in a good-quality reservoir in the Lower Cenomanian objective in the Cayar Offshore Profond Block, the company said May 9.
The Cayar Offshore Profond Block is in about 1,800 m of water.
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, and discovered about 25 trillion cubic feet (Tcf) of resources; there could be more than 50 Tcf of resource potential in the fairway.
Kosmos holds a 60% interest in the Teranga-1 well; Timis Corp. Ltd. holds 30% and Societe des Petroles du Senegal (Petrosen) 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.
Kosmos Energy has U.S. headquarters in Dallas.
Favorable economics could push forward planned projects as more come online.
Vast gas resources offshore Mauritania and Senegal will benefit the two African countries and spur exploration, the CEO of Kosmos said.
