Located in the Cayar Offshore Profond block approximately 40 mi (65 km) northwest of Dakar in nearly 5,906 ft (1,800 m) of water, the Teranga-1 well was drilled to a total depth of 14,715 ft (4,485 m).
The well encountered 31 m (102 ft) of net gas pay in good-quality reservoir in the Lower Cenomanian objective. Well results confirm that a prolific inboard gas fairway extends approximately 124 mi (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.
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 CEO, 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.”
