Kosmos makes second gas discovery offshore Mauritania

Kosmos Energy Ltd., Dallas, reported making a second natural gas discovery offshore Mauritania with its Marsouin-1 exploration well, drilled in 2,400 m of water in the northern part of Block C-8.

The discovery, which Kosmos called “significant” and “play-extending,” was drilled 60 km north of the company’s basin-opening Tortue-1 well (renamed Ahmeyim), which was also drilled on Block C-8 and intersected 351 ft of net hydrocarbon pay in the primary Lower Cenomanian objective (OGJ Online, Apr. 27, 2015).

Based on preliminary analysis of drilling and wireline logging results, Marsouin-1 encountered at least 230 ft of net gas pay in Upper and Lower Cenomanian intervals, the company said.

The Atwood Oceanics Atwood Achiever drillship will now proceed to the Ahmeyim-2 location in the southern part of Block C-8, where it will drill the top-hole section of the well. The drillship is then expected to go to Senegal, where it will spud Guembeul-1, the first in a series of wells to delineate the Greater Tortue area, before yearend.
