BW Energy has confirmed a substantial oil discovery at the Bourdon prospect in the Dussafu Licence offshore Gabon, following the successful drilling of the second sidetrack, DBM-1 ST2. The appraisal well has demonstrated good reservoir and fluid quality, supporting the initial discovery announced on 7 March 2025. Management estimates indicate approximately 56 million barrels of oil in place, with around 25 million barrels considered recoverable.

“The appraisal well confirms the potential for establishing a new development cluster with a production facility following the MaBoMo blueprint. We expect at least four producing wells,” said Carl K. Arnet, CEO of BW Energy. “We continue to successfully expand the Dussafu reserve base which, together with multiple additional prospects yet to be drilled, will support long-term production and value creation in Gabon.”

Initial data from the appraisal shows that oil from the Bourdon field has the lowest viscosity among Dussafu discoveries, with an average measurement of 3.5 centipoise, compared to 5 cp and 7 cp at the Hibiscus/Tortue and Ruche fields, respectively.

Logging data and formation pressure measurements confirm approximately 11.2 metres of pay within an overall hydrocarbon column of 35.2 metres in the Gamba formation. The DBM-1 ST2 well was drilled by the Norve jack-up rig to a total depth of 4,731 metres.

The Bourdon discovery is located approximately 15 kilometres west of the FPSO BW Adolo and 7.5 kilometres southeast of the MaBoMo facility. The find will enable BW Energy to book additional reserves not included in its 2024 Statement of Reserves.
