Kosmos Energy completed drilling its latest well offshore Mauritania, the Lamantin-1 exploration well. The well is located on Block C-12 in water depths of approximatly 2,200 meters.
The well was drilled to a total depth of 5,150 meters and was designed to evaluate a previously untested Lower Campanian base of slope fan supplied from the Nouakchott River system. As interpreted from logs and samples collected during drilling and wireline operations, Kosmos’ evaluation suggests the Campanian reservoir objective was water bearing with some residual hydrocarbons.
The company said in a statement that it believes the prospect failed due to a lack of trap, related to a combination of up-dip sand pinch-out and top/base seal effectiveness. The well will now be plugged and abandonded and the well results integrated into the ongoing evaluation of the significant remaining prospectivity in Kosmos’ large acreage position.
The company will now move the drillship to the next well in the program, the Requin Tigre prospect offshore Senegal. The Requin Tigre prospect is a Cenomanian/Albian base of slope fan supplied from the proven Senegal River system.
