Following the disappointing results of its Hibiscus Extension (DHIBM-2) well on the Dussafu Marin permit earlier this year, BW Energy has discovered oil at Hibiscus North via the DHBNM-1 exploration well.
The well had a geological analogue to the Ruche Field, where the Gamba structure was the primary target, and had estimated potential reserves of 10 to 40 million barrels of oil. However, upon completion of drilling by the Borr Norve Jack-up, reserves found were below the lower end of that pre-drill resource estimate.
Discovered reserves will add up to the overall resource estimates of the shallow water Dussafu Marin permit where production started in 2018 from the Tortue field, and could potentially support a tie-back in the future. The overall license produced an average of 10,500 barrels of oil per day (bopd) in Q2 2021 and is a critical asset to maintain Gabon’s oil & gas output.

BW Energy is currently preparing to execute a third development phase on the block with the Ruche Phase 1 project, which will follows Tortue Phase 1 and Tortue Phase 2. The Ruche development targets the Hibiscus and Ruche Fields located 20km northwest of the Tortue Field via the drilling of up to six horizontal production wells connected to a fixed wellhead platform, itself tied back to the existing BW Adolo FPSO. Current production forecasts expect a production peak of 39,000 bopd in 2024 when Tortue Phase 2 and Ruche Phase 1 are completed.
Details on the development of the Dussafu Marin Permit are available in the “Projects” section within your Hawilti+ research terminal.
