Kosmos Energy, Dallas, continues to evaluate oil prospects across Mauritania and Senegal ahead of the next phase of exploration offshore the two countries despite results of its latest exploration well.
The well, Requin Tigre-1, was drilled in Senegal’s Saint Louis Offshore Profond block to 5,200 m total depth and was designed to evaluate Cenomanian and Albian reservoirs in a structural-stratigraphic trap charged from an underlying Neocomian-Valanginian source kitchen. The well encountered no hydrocarbons.
Post-well analysis continues as the company believes there is “substantial remaining prospectivity” in its acreage position.
The Reguin Tigre well was the last in the second phase of exploration of the deepwater Cretaceous petroleum systems in the area, targeting large basin floor fan structures, said Kosmos Energy Chairman and Chief Executive Officer Andrew G. Inglis. The company drilled 4 wells in the second phase, with success at Yakaar (OGJ Online, May 8, 2017).
In Phase 1, targeting inboard structures on the slope, the company encountered hydrocarbons in its three test wells: Tortue, Marsouin, and Teranga (OGJ Online, Aug. 17, 2017; May 9, 2016; Nov. 12, 2015).
“Overall we have discovered gross resource of 40 tcf, at a net cost of 20¢/boe benefiting from the partner carry, and have created the potential for two world scale LNG hubs,” Inglis said.
Kosmos was fully carried on the cost of the Requin Tigre well.
The drillship will proceed with plans to test two oil prospects offshore Suriname starting early in this year’s second quarter.
Kosmos holds 30% participating interest in the Saint Louis Offshore Profond license. BP PLC holds 60% participating interest (OGJ Online, Dec. 19, 2016). State oil concern Petrosen holds 10%.
