Kosmos Energy has made a gas discovery at its Teranga-1 exploration well in the Cayar offshore profond block, 65km north-west of Dakar, Senegal, at depths of 1,800m.
The Teranga-1 well was drilled to a total depth of 4,485m and encountered 31m of net gas pay in good quality reservoir in the Lower Cenomanian objective.

Results confirmed the extension of a prolific inboard gas fairway, 200km from Marsouin-1 well in Mauritania through the Greater Tortue area on the maritime boundary to Teranga-1 well.
Kosmos drilled five consecutive exploration and appraisal wells in this fairway, discovered a gross Pmean resource of about 25 trillion cubic feet.
The fairway is expected to hold more than 50 trillion cubic feet of resource potential.
Kosmos Energy chairman and CEO Andrew Inglis said: "Our continuing exploration success demonstrates we have opened a super-major scale basin offshore Mauritania and Senegal with world-class resource potential.

By GlobalData"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."
The Teranga-1 exploration well is 60% owned by Kosmos, while Timis owns 30% and the remaining 10% is owned by Société des Pétroles du Sénégal (Petrosen).
In March, Kosmos made a gas discovery at its Ahmeyim-2 appraisal well in the offshore area of Mauritania and Senegal.
The well is located in Mauritanian waters, 5km north-west, and 200m downdip of the basin-opening Tortue-1 discovery well. It was drilled to a total depth of 5,200m.
