BW Offshore confirmed oil pay in the western flank of Tortue field with its DTM-3 appraisal well in the Dussafu license offshore Gabon.

The well, drilled to 3,550 m TD, penetrated 30 m of hydrocarbon pay in the Early Cretaceous Gamba formation and underlying Dentale Subcrop sandstone at a structural position matching the predrill estimate. It hit additional hydrocarbon pay in the Dentale D2B and Dentale D6 reservoirs.

The DTM-3 well followed completion of the DTM-2H horizontal production well targeting the Dentale D6 reservoir in April. Additional development drilling is likely, including a horizontal development well, the DTM-3H, which will target the Gamba sandstone in the central part of the field, the company said.

Production is to start in the second half of the year, said BW Offshore Chief Executive Officer Carl K. Arnet (OGJ Online, Feb. 24, 2017).

The Dussafu licence is operated by BW Offshore subsidiary BW Energy.
