The Dussafu Area Contains Five Pre-Salt Oil Discoveries and Various Additional Prospects and Leads
BW Offshore announced on Monday that the first oil extraction from the BW Adolo FPSO was successfully achieved on September 16, 2018, 18 months after the initial investment was made in the Dussafu license off Gabon. “We achieved first oil from the Dussafu license on budget and on schedule,” said Carl K. Arnet, CEO of BW Offshore. “The execution of the Dussafu project confirms the attractiveness of our model by combining proven resources, an ingenious organization, and access to producing assets to achieve a short time to oil.”
The Adolo FPSO had previously worked in the Azurite field but was subsequently selected by BW for the development of Tortue. The FPSO unit was prepared for deployment at Tortue by a Keppel shipyard in Singapore and was officially named FPSO BW Adolo in early April.
The BW Adolo arrived in Gabon at the end of July and connected the anchoring systems, and the installation of risers and umbilicals was completed in September.

The FPSO is installed in the Tortue field, one of the five proven discoveries in the Dussafu license. The BW Adolo is a converted VLCC with a production capacity of 40,000 barrels of oil per day. The vessel underwent a significant life extension scope, allowing for an expanded production profile based on positive reserve developments.
Arnet stated that the priority now is to complete start-up activities and stabilize production at the BW Adolo.
He added: “At the same time, we will work towards the final investment decision on Tortue Phase 2, which will unlock additional production volumes, and we will continue with the evaluation program for the recently announced discovery at Ruche NE, as well as confirm additional resources and strengthen the commerciality of the Dussafu license,” said Carl K. Arnet.
Results Will Be Available Soon
Dussafu is an Exclusive Exploration Area (“EEA”) of 850 square kilometers located in southern Gabon. The area is valid for 20 years from the first oil production. It contains 5 pre-salt oil discoveries and various additional prospects and leads. Dussafu is operated by BW Energy, and Panoro Energy holds an 8.333% interest.
The development concept involves a current phase 1 consisting of two horizontal wells tied to the BW Adolo FPSO.
John Hamilton, CEO of Panoro Energy, said: “Achieving first oil at Tortue is an important milestone for Panoro, having been involved in the evolution of the Dussafu PSC, from oil discoveries to modern interpretation after the seismic acquisition and now to first commercial production. We are extremely pleased with all stakeholders in this important producing asset in Gabon, and the commencement of oil production at Dussafu represents a significant achievement for Gabon and the Dussafu project team.”
Further announcements will be made in due time regarding production rates and planning for Tortue Phase 2. Additionally, the recently successful well at Ruche North East is currently being evaluated following a lateral track and extensive logging. Results will be announced in the near future, Panoro said.
