StockMarketWire.com - Kosmos Energy has completed drilling the Lamantin-1 exploration well located in block C-12 offshore Mauritania in approximately 2,200 metres of water. Lamantin-1 was drilled to a total depth of 5,150 m and was designed to evaluate a previously untested Lower Campanian base of slope fan supplied from the Nouakchott River system, trapped in a combination structural-stratigraphic feature, and charged from underlying, oil-prone Cenomanian/Turonian and Albian source rocks.

Kosmos said: 'As interpreted from logs and samples collected during drilling and wireline operations, our evaluation suggests the Campanian reservoir objective was water bearing with some residual hydrocarbons.

'We believe 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 abandoned and the well results integrated into the ongoing evaluation of the significant remaining prospectivity in Kosmos's large acreage position. Chairman and chief executive Andrew G. Inglis said: 'We are still in the early stages of exploring this newly emerging basin and our forward drilling programme remains unchanged given the independent nature of the prospects.

'The drillship will now proceed as planned to test the independent Requin Tigre prospect offshore Senegal, which will be followed by two high-impact oil tests offshore Suriname in mid-2018.'
