The TEN project is 99 per cent complete, Kosmos Energy, one of the partners working in Ghana’s Jubilee oil fields in the Western Region, has said.
The TEN Project is Tullow’s second development following the record delivery of the Jubilee field in 2010. It is expected to produce up to 80,000 barrels of oil per day.
Operated by Tullow, the TEN Project takes its name from the three offshore fields under development – Tweneboa, Enyenra and Ntomme – which are situated in the Deepwater Tano block, around 60km offshore Western Ghana.
In its second-quarter report, Kosmos said: “The TEN project remains on schedule and on budget, with the project now 99% complete and expected to deliver first oil shortly, consistent with the operator’s guidance.
“Eight of the eleven previously drilled wells have now been completed. Hook-up and commissioning of the FPSO, connecting the pre-drilled wells to the vessel via the subsea infrastructure, is nearing completion.”
The update said a gradual ramp-up in oil production towards the FPSO capacity of 80,000 bopd is anticipated around the end of 2016 as the facilities complete performance testing and well production levels are increased to optimal rates.
Per operator guidance, average annualised production from TEN in 2016 is expected to be approximately 23,000 bopd gross during the year, which equates to an average of approximately 55,000 bopd while it is online in 2016.
Associated gas production at TEN is expected to be re-injected into the Ntomme reservoir gas cap until gas export begins.
Gas export was planned to commence 12 months after field start up, with the Tweneboa gas reservoir coming onstream a further 12 months later.
However, plans to accelerate gas export are currently under evaluation as the fabrication of the gas export facilities has been completed early and can be installed by year end, allowing connection to the existing gas infrastructure early in 2017, the energy firm added.
During the second-quarter, Kosmos announced that it had entered into a farm-out agreement with a wholly-owned subsidiary of the Hess Corporation (NYSE:HES) covering the Block 42 contract area offshore Suriname. Kosmos and its partners in Suriname expect to commence a 6,500 square kilometre 3D seismic survey during the third-quarter.
