BW Energy Ltd. has made an oil discovery in the Hibiscus North exploration well (DHBNM-1) in the Dussafu block offshore Gabon. After reaching total depth, logging operations and evaluation of the oil discovery will be undertaken, which will be followed by the drilling of a sidetrack to delineate the field.
The discovery is expected to add to the previously announced gross discovered recoverable resource estimate of 105 million bbl for the block.
The well lies about 6 km north-northeast of the Hibiscus discovery well DHIBM-1 in about 115 m of water. It will be drilled to a planned total depth of about 3,500 m.
The well, part of a three-well campaign on the license, was spudded on July 28 (OGJ Online, May 10, 2021). During drilling operations, the Gamba reservoir was encountered at a depth of 2,794 m and encountered about 13.5 m of oil-bearing reservoir in the Upper Gamba sandstone. Determination of the overall hydrocarbon column is pending open hole wireline logging operations which will be conducted after drilling to planned total depth.
The Borr Norve jack up rig is continuing drilling operations to intersect the secondary targets in the deeper Dentale formation.
BW Energy is operator of the 850-sq km Dussafu block with 73.5% interest. Panoro Energy holds 17.5% and the Gabonese Oil Co. holds 9%.
