DALLAS – Kosmos Energy will P&A its Lamantin-1 exploration well in block C-12 offshore Mauritania after encountering only water.
The well, in 2,200 m (7,218 ft) water depth, was drilled to a TD of 5,150 m (16,896 ft), and was designed to assess a previously untested Lower Campanian base of slope fan supplied from the Nouakchott River system, thought to be charged from underlying, oil-prone Cenomanian/Turonian and Albian source rocks.
Kosmos said the prospect failed probably due to a lack of trap, related to a combination of up-dip sand pinch-out and top/base seal effectiveness.
Chairman and CEO Andrew G. Inglis said the company’s forward drilling program remained unchanged in view of the independent nature of the prospects.
The drillship will next drill the Requin Tigre prospectoffshore Senegal, a Cenomanian/Albian base of slope fan supplied from the proven Senegal River system.
The location is roughly 150 km (93 mi) offshore in 3,100 m (10,170 ft) water depth, 60 km (37 mi) west of the Tortue gas discovery, and 80 km (49.7 mi) north of theYakaar discovery. Drilling should take around 60 days to complete.
Thereafter, Kosmos plans two potentially high-impact wells targeting oil offshore Suriname in mid-2018.
