Oil and gas company BP and its partner Kosmos Energy have taken a final investment decision (FID) on the first phase of the Greater Tortue-Ahmeyim offshore gas project, which straddles the maritime boundaries of Mauritania and Senegal. The field will produce gas from an ultra-deepwater subsea system and then ship it to a 2.5 Mt/year (3.4 bcm/year) floating LNG (FLNG) plant, which will process the gas for Senegal, Mauritania and exports to global markets, with potential for expansion to 10 Mt/year.
The Greater Tortue and Ahmeyim fields are estimated to hold around 15 tcf (around 425 bcm) of gas and their resources will be equally split between the two countries. BP and Kosmos plan to move the project through the development phase to production by the first half of 2022.
BP farmed in at the end of 2016 and holds a significant part of the project while Kosmos Energy, Société des Pétroles du Sénégal (Petrosen) and Société Mauritanienne des Hydrocarbures et de Patrimoine Minier (SMHPM) hold the remainder. Equity interests differ according to the country: in Mauritania, BP holds a 62% in the project, while Kosmos Energy holds 28% and SMHPM 10%. In Senegal, BP detains 60%, while Kosmos Energy and Petrosen hold respectively 30% and 10%. As for the Tortue unit, the stakes are different again: BP holds a 61% interest while Kosmos Energy, Petrosen and SMHPM hold respectively 29%, 5% and 5%.
