Kosmos Energy has not encountered hydrocarbons after completion of a drilling campaign at the Requin Tigre-1 exploration well in Senegal’s Saint Louis Offshore Profond block.

The company drilled Requin Tigre-1 to a total depth of 5,200m with its partner BP.

The drilling campaign at the well was aimed at evaluating Cenomanian and Albian reservoirs in a structural-stratigraphic trap, charged from an underlying Neocomian-Valanginian source kitchen.

Even after fully testing the prospect, hydrocarbons were not discovered and post-well analysis is currently ongoing to identify the reasons.

Kosmos Energy chairman and CEO Andrew Inglis said: “With each exploration well drilled, we deepen our understanding of this newly emerging basin, further refining our geologic model and geophysical tools.

“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.

“With each exploration well drilled, we deepen our understanding of this newly emerging basin.”

“We have delivered one success (Yakaar) in four wells in this second phase programme, following three successes in three wells (Tortue, Marsouin, Teranga) in the first phase programme targeting inboard structures on the slope.”

Until now, Kosmos has discovered gross resource of 40 trillion cubic feet.

The company is planning to evaluate its inventory of prospects across Mauritania and Senegal before proceeding with the next phase of exploration offshore the two countries.

The drillship will move to test two oil prospects offshore Suriname beginning in the early second quarter of this year.

Kosmos holds a 30% participating interest in the Saint Louis Offshore Profond licence, while BP has a 60% interest.

The remaining 10% interest is held by national oil company Société des Pétroles du Sénégal.
