Kosmos, partners reach Tortue offshore gas field FID

Kosmos Energy and its partners have made a final investment decision to proceed with Phase 1 of the Greater Tortue Ahmeyim natural gas project offshore Mauritania and Senegal. The project will produce gas from a deepwater subsea system and mid-water floating production, storage, and offloading vessel to a 2.5-million tonne/year (tpy) 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. BP Gas Marketing will buy LNG offtake from Greater Tortue Ahmeyim Phase 1.

Phase 1 will move into detailed design and construction—with awarding of engineering, procurement, construction, and installation contracts—following final regulatory and contract approvals. Project execution is expected to begin first-quarter 2019.

Kosmos holds a 29% stake the Tortue unit with partners BP (61%), Senegal-state Petrosen (5%), and Mauritania-state SMHPM (5%). Mauritania and Senegal agreed to joint development of the field in early 2018 (OGJ Online, Feb. 12, 2018).
