New discovery expands natural gas resource potential offshore Mauritania, Senegal

DALLAS -- Kosmos Energy has announced that the Greater Tortue Ahmeyim-1 well (GTA-1), drilled on the eastern anticline within the unit development area of Greater Tortue, has encountered approximately 30 m of net gas pay in high-quality Albian reservoir. The Greater Tortue Ahmeyim LNG project is on track to deliver first gas in the first half of 2022, and the well (which has been designed as a future producer) will be used to further optimize the development drilling plans for the BP-operated project.

Commenting on the results of the GTA-1 well, Chairman and CEO Andrew G. Inglis said: “The GTA-1 well confirms our expectation that the gas resource at Greater Tortue Ahmeyim will continue to grow over time and could lead to further expansion of this world-scale 10 MTPA LNG project. In addition, Kosmos’ process to sell down its interest to 10% has received considerable interest from the industry, with initial bids expected over the summer, and transaction conclusion anticipated by year end.”

Located offshore Senegal the GTA-1 well was drilled in approximately 2,500 m of water, approximately 10 km inboard of the Guembeul-1A and Tortue-1 wells, to a TD of 4,884 m.

The Ensco DS-12 rig, working on behalf of the operator BP, will now drill the Yakaar-2 appraisal well in Senegal, which is expected to spud in the coming weeks, before drilling the Orca-1 exploration well in Mauritania, which is expected to spud late in the third quarter.

Partners in the cross-border Greater Tortue Ahmeyim project, located offshore Mauritania and Senegal, include SMPHM, Petrosen, BP, and Kosmos.
