BW Energy appraisal wells support additional Dussafu development

BW Energy says two appraisal wells at Gabon’s Dussafu licence confirmed commercial oil volumes with combined gross recovery estimated at 8–9 million barrels. The findings support adding at least one production well to the MaBoMo Phase 2 campaign, rather than representing oil already produced. Well 10P2 encountered a 30-metre oil column in the Gamba reservoir. Logging and pressure tests suggest a future production well could initially deliver more than 5,000 barrels per day gross, with base-case recovery of six million barrels. Well 10P1 found a separate accumulation with a 16-metre oil column, supporting a further production well whose timing remains to be determined. The rig is moving to MaBoMo to replace an electrical submersible pump on an existing Hibiscus well before drilling four Phase 2 production wells and a fifth at 10P2. Phase 2 targets first oil in the first quarter of 2027 and up to 20,000 barrels per day gross at peak. BW Energy owns 73.5% of Dussafu, alongside Panoro Energy’s 17.5% and Gabon Oil Company’s 9%. The subsequent schedule includes an infill well at Tortue and Bourdon Phase 1, where first oil is targeted for the first quarter of 2028. BW Energy's longer-term Dussafu ambition is 30,000–45,000 barrels per day gross, with Walt Whitman and further Bourdon appraisal planned for 2028. The source also reports a recent licence extension, without specifying its duration. All these dates and volumes remain company plans or estimates. The projected recovery at 10P2 is not the same measure as an initial daily flow rate or a sustained field production level. Nexus analysis: The appraisal results support a larger drilling programme, but delivery depends on converting reservoir estimates into producing wells; sequential starts explain why individual well rates cannot simply be added together.
