Oslo-listed BW Energy on Wednesday said it has launched production from the Tortue Phase 2 field development on the Dussafu Marin license offshore Gabon.

Two production wells were completed and turned over to production operations, with the DTM-7H well in the Gamba formation successfully brought online on 19 October.

The DTM-6H well in the Dentale formation is scheduled to come on stream in the coming days.

Production prior to the two new production wells was around 11,500 barrels per day of oil, according to the company.

The Tortue development consists of six production wells, tied back to BW Offshore's Adolo floating production, storage and offloading vessel.

Completion of the two wells was suspended last year due to the Covid-19 pandemic.

“The Tortue Phase 2 development was completed below budget and within the revised timeframe. We look forward to the production growth following first oil from the two wells," said BW Energy chief executive Carl Arnet.

"Operationally we will now focus on stabilisation of the production and wrapping up the project activities," he added.

BW Energy noted that gross production from the Tortue field averaged approximately 9000 bpd in the third quarter of 2021, amounting to a total gross production of 800,000 barrels of oil for the period.

The decrease in production was mainly due to plant shutdowns and temporary operational issues, with the company noting that a shortage of gas lifting capacity impacted production.

A nitrogen generation unit has been installed on BW Adolo FPSO to improve production efficiency.

BW Energy operates Dussafu with a 73.5% interest, with Panoro on 17.5% and the state-owned Gabonese Oil Company on 9%.
