Kosmos Energy, Dallas, signed a contract with BP Gas Marketing Ltd., a subsidiary of BP Plc, for the supply of 2.45 million tonnes/year (mtpy) of LNG from Phase 1 of the Greater Tortue Ahmeyim natural gas project offshore Mauritania and Senegal for an initial 20-year term.
The Greater Tortue Ahmeyim Phase 1 development was sanctioned in December 2018 (OGJ Online, Dec. 21, 2018). The project will produce gas from a deepwater subsea system and mid-water floating production, storage, and offloading vessel to a 2.5-million mtpy floating LNG unit at a nearshore hub on the Mauritania and Senegal maritime border. Kosmos estimates total recoverable gas in the field at around 15 tcf.
The project will provide LNG for export, as well as make gas available for domestic use in both Mauritania and Senegal. First gas for the project is expected first-half 2022.
Following signing of the agreement, Kosmos intends to book net proved reserves of 100 MMboe associated with Phase 1, as evaluated by reserve auditor Ryder Scott Co. LP.
Tortue Ahmeyim field development is on the C-8 block offshore Mauritania and the Saint-Louis Profond block offshore Senegal. BP operates Tortue with 61%. Partners are Kosmos 29%, Senegal-state Petrosen 5%, and Mauritania state firm SMHPM 5%.
