BW Energy Limited has said that the company has discovered huge oil deposit in the Hibiscus North exploration well (DHBNM-1) in the Dussafu Block offshore Gabon. The well is located approximately 6 km north-northeast of the Hibiscus discovery well DHIBM-1 in approximately 115 metres of water depth. The well will be drilled to a planned total depth of approximately 3500m.
It is expected that the discovery will add to the previously announced gross discovered recoverable resource estimate for the block, which is currently estimated to be approximately 105 million barrels gross. The Company announced the spudding of the well on 28 July 2021.
During the drilling operations at Hibiscus North, the Gamba was encountered at a depth of 2794m meters and encountered approximately 13.5m 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 the well to the planned total depth.
The Borr Norve Jack-up is continuing drilling operations to intersect the secondary targets for the exploration well in the deeper Dentale Formation.
After reaching total depth, logging operations and evaluation of the oil discovery will be undertaken; this will be followed by the drilling of a side-track to delineate the field.
The Dussafu Block is 850 square km. BW Energy is operator and holds 73.5% interest in the Block. Panoro Energy holds 17.5% interest and the Gabonese Oil Company holds 9%.
