BW Energy concludes Tortue Phase 2 project offshore Gabon

BW Energy Ltd. hooked up the final two production wells DTM-6H and DTM-7H in the Dussafu Marin license offshore Gabon and has completed handover to production operations, concluding the Tortue Phase 2 project.

Gambia Well DTM-7H was brought online on Oct. 19. DTM-6H, in the Dentale formation, is scheduled to come onstream in the coming days. Current production prior to the two new production wells is around 11,500 b/d.

The Tortue development consists of six production wells, tied back to the BW Adolo FPSO (OGJ Online, May 10, 2021). Completion of DTM-6H and DTM-7H wells were suspended last year due to the COVID-19 pandemic.

Gross production from Tortue field averaged about 9,000 b/d in third-quarter 2021, amounting to a total gross production of 800,000 b/o for the period. The decrease in production compared to second-quarter 2021 was mainly due to plant shutdowns and temporary operational issues, the company said. A shortage of gas lifting capacity also impacted production. A nitrogen generation unit has been installed on BW Adolo to improve production efficiency, the company said.

BW Energy had a cash balance of $170 million at Sept. 30 compared to $216 million at June 30. The decrease is mainly due to investment activities related to Tortue Phase 2, progress on the Hibiscus-Ruche project, as well as completing the exploration drilling campaign in Dussafu.

BW Energy is operator of the 850-sq km Dussafu block with 73.5% interest. Panoro Energy holds 17.5% and the Gabonese Oil Co. holds 9%.
