Kosmos Energy says it plans to reduce its stake in the Tortue gas development to around 10%. “Kosmos has discovered a significant and valuable resource in Mauritania and Senegal and the final investment decision of the Tortue project in December 2018 has created a value inflection point. Following interest from multiple third parties, Kosmos intends to sell down its position to ~10%,” the company said in a capital markets day presentation on 25 February.
