Oil and gas exploration company, Kosmos Energy Ltd. KOS recently announced that it has decided to start the drilling of three new wells offshore Senegal and Mauritania by the end of this month. This follows the gas discovery off the coast of Senegal at the beginning of 2017. The company will start spudding of its three super-giant prospects with the Hippocampe well near Senegal.
To date, Kosmos Energy has drilled six wells off the coast of West Africa, where it has found around 40 trillion cubic feet of gas equivalent (Tcfe). The company believes that along the Atlantic margin, the Mauritania-Senegal offshore belt is the largest petroleum system found in last 15 years. Backed by the new seismic data gathered by Kosmos, the company believes that the resource base it has discovered will keep growing with more drilling.
Kosmos Energy's Drilling Plan
The company is presently working on the Yakaar-1 well offshore Senegal, where the company made a discovery in May 2017. The well with a depth of about 4,700 meters is located in the Cayar Offshore Profond block, where Kosmos has engaged the Atwood Achiever drillship.
Upon the closure of operations at the Yakaar-1 well, the company will move the drillship to Tortue-1, another Kosmos discovery, to perform a drill stem test. The company will then mobilize the Atwood Achiever drillship to drill the Hippocampe well, the first of the trio, which has 12 Tcfe gross unrisked resource potential. It is located in Block C-8, northwest and outboard of the Marsouin discovery. It has a large basin floor fan with extensive, stacked reservoirs of Cenomanian and Albian age, making it easy for Kosmos to extract. Kosmos Energy expects to begin the drilling of Hippocampe well by the end of Aug 2017.
The drillship will next move to Lamantin by the fourth quarter, the company's youngest prospect. The seismic tests have led Kosmos Energy to believe that Lamantin has black oil in its reservoir as it is from the Albian geologic timescale. Lamantin has an estimated p-mean resource size of 2-3 billion barrels of oil equivalent.
The company will reach its third prospect, Requin Tigre, by the end of 2017. It is located in northern Senegal and has 60 Tcfe gross unrisked resource potential. The prospect is from the Cenomanian geologic timescale.
