DALLASKosmos Energy has completed drilling its latest deepwater exploration well offshore northwest Africa.

As with the company’s previous two wildcats offshore Mauritania, the Requin Tigre-1 well, in Senegal’s Saint Louis Offshore Profond block, did not deliver hydrocarbons.

It was designed to evaluate Cenomanian and Albian reservoirs in a structural-stratigraphic trap, charged from an underlying Neocomian-Valanginian source kitchen.

Kosmos is analyzing the results to determine why the well was unsuccessful, in the hope of improving its understanding of the deepwater Cretaceous petroleum systemsoffshore Mauritania and Senegal.

The company believes there is substantial remaining prospectivity in its acreage in this region.

Andrew G. Inglis, Kosmos’ chairman and CEO, said: “Requin Tigre was the last well in our second phase of exploration of the deepwater Cretaceous petroleum systems offshore Mauritania and Senegal targeting large basin floor fan structures. We have delivered one success (Yakaar) in four wells in this second phase program, following three successes in three wells (Tortue, Marsouin, and Teranga) in the first phase program targeting inboard structures on the slope.

“Overall we have discovered a gross resource of 40 tcf, at a net cost of $0.20 per barrel of oil equivalent benefiting from the partner carry, and have created the potential for two world-scale LNG hubs.

“We will rigorously evaluate our large inventory of prospects across Mauritania and Senegal ahead of the next phase of exploration offshore the two countries.”

Kosmos has a 30% interest in the Saint Louis Offshore Profond license, with BP holding 60% and state-owned Société des Pétroles du Sénégal (Petrosen) 10%.

The drillship will now head west as planned to test two oil prospects offshore Suriname, starting in early 2Q.
