GABON

BW Energy has announced the resumption of a three-well drilling campaign on the Dussafu license offshore Gabon, which consists of two exploration wells in the Hibiscus area and one production well on the Tortue field. The current campaign will start with the Hibiscus Extension appraisal well (DHIBM-2), located about 56km from the coast in 119m water depth. The well is planned as a vertical well to test the northern extension of the Gamba reservoir within the existing Hibiscus field discovery.

If hydrocarbon is present in the well, a few appraisals side-track wells may be drilled to further search the field. The appraisal well will provide new input to the ongoing Hibiscus/Ruche development project, currently based on the already discovered 46.1 million barrels gross 2P reserve at Hibiscus and the 24.1 million barrels at Ruche and Ruche North East. The development project plan will consist of a converted jack-up rig tied back to the floating production storage and offloading with 12 development wells drilled in two phases, with the first oil expected in Q1 2023.

The additional reserves at Hibiscus, if proven by DHIBM-2, may lead to the relocation of the first converted jack-up and the potential deployment of a second converted jack-up to further exploit the resources in this prolific area of Dussafu. The timing of the first oil from the region would not be affected. Following the DHIBM-2 well, the rig will move to drill the horizontal production well, DTM-7H, at the Tortue field. Once DTM-7H is completed and hooked up along with the previously drilled DTM-6H well, this will complete the phase 2 development of Tortue and will bring the total number of producing wells at Tortue to 6.

The rig will subsequently move to drill the Hibiscus North prospect, located approximately 6km north-northeast of the DHIBM-1 well. Hibiscus North is a separate prospect with estimated potential reserves ranging between 10 to 40 million barrels of oil which could further enhance the resource base of the Hibiscus/Ruche area.
