Jubilee FPSO switched to new heading
Tullow Oil says the turret remediation project for the Jubilee FPSO offshore Ghana is close to completion.
The program, said to have included the first ever remediation of this type at sea, involved shutting down the FPSOKwame Nkrumah twice in the first half of 2018 for work to stabilize the turret bearing, for 19 and 21 days respectively.
Last December, the vessel was successfully rotated to its new heading of 205° and subsequently spread-moored.
In addition, the field partners have agreed to install a catenary anchor leg mooring buoy for offtake from the FPSO and have awarded a contract. Installation should follow in 2020 and this activity should not impact production.
Tullow has pre-qualified for Ghana’s first ever international licensing round with bids due by mid-May. The licensing process should conclude by the end of August.
The company continues to reprocess 3D seismic data over block CI-524 offshore Côte d’Ivoire, alongside the maritime border with Ghana and next to Tullow’s operated TEN fields.
Off Mauritania to the northwest, Tullow has a 15% stake in block C18, where a 9,300-sq km (3,591-sq mi) 3D seismic survey was completed last year.
The data is currently undergoing interpretation ahead of a drill-or-drop decision in April. Over block C3, where Tullow has a 100% operated stake, it has been interpreting 3D data captured in 2017 to assess prospects for a potential well in 2020.
Across the Atlantic, the company and its partners are negotiating for a drillship to drill on the Orinduik blockoffshore Guyana.
The first well will target theJethro prospect. In addition, the company expects to participate during 3Q in a well on the Carapa prospect in the Repsol-operated Kanuku license.
Elsewhere, Tullow is interpreting results from a 3D seismic survey acquired over its acreage offshore Jamaica to mature prospects. Drilling could start in 2020.
The company has decided not to enter the next term of the block 15 exploration license offshore Uruguay as it believes the potential prospects are too high risk. It plans to exit the license next month.
Finally, Tullow expects to complete decommissioning of all its remaining operated UK North Sea wells by this summer. It will then embark on final removal and clearance activities to restore the seabed.
Decommissioning of all the company’s non-operated UK North Sea assets should finish by 2025.
