Kosmos Energy Ltd. encountered 31 m of net natural gas pay in its Teranga-1 well in the Cayar Offshore Profond block about 65 km northwest of Dakar, Senegal.
The well was drilled to a total depth of 4,485 m and encountered good-quality reservoir in the Lower Cenomanian formation. Well results confirm that a prolific inboard gas fairway extends 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 said. The Marsouin-1 was Kosmos’ second Mauritanian discovery (OGJ Online, Nov. 12, 2015).
The company has discovered gross P-mean resources of 25 tcf in the current fairway with five consecutively successful appraisal wells. Kosmos holds a 60% interest in the Teranga-1well, along with Timis Corp. Ltd. 30% and Societe des Petroles du Senegal (Petrosen) 10%.
