ENERGY giant BP and Kosmos Energy are to develop a massive offshore gas field that is located between Senegal and Mauritania in West Africa. Liquefied natural gas technology is being utilised to commercialise those resources, as the sheer size of the Tortue gas field means those supplies need to gain access to hungry customers in Asia and Europe.
For Kosmos Energy, this development is its largest ever and marks the beginning of its journey to becoming a medium-sized upstream offshore player. For BP, this development is part of its ongoing strategy to shift its upstream production mix from a 50/50 split between oil & gas to one that is 40 percent oil and 60 percent gas by the 2020s.
Kosmos Energy discovered the offshore Tortue gas field back in April 2015 through the Tortue 1 exploration well. Subsequent appraisal activity indicated the prospect was one large gas field. The discovery was rebranded as the Greater Tortue Ahmeyim complex, which consists of Tortue West, Tortue East, and Tortue North reservoirs. Kosmos Energy, as the operator of the exploration side of the venture, estimates the field houses at least 15 trillion cubic feet (Tcf) of recoverable natural gas resources. There is room for upside as the Greater Tortue Ahmeyim complex may house up to 50 Tcf of recoverable gas resources and an additional 1 billion barrels of recoverable liquids hydrocarbons (condensate and liquefied petroleum gas).
Due to Kosmos Energy’s exploration success, BP bought into the play in late 2016 in a deal valued at almost $1bn at the time. BP will be the operator of any development activities at the play, and Kosmos Energy will remain operator of the exploration activities.
