Jubilee field

Ghana’s world-class Jubilee field was discovered in 2007 by the Mahogany-1 (M-1) and Hyedua-1 (H-1) exploration wells.

The two wells were drilled some 5 km apart and intersected large continuous accumulations of light sweet crude oil. The M-1 and H-1 wells discovered large net pays of 95m and 41m respectively in high-quality stacked reservoir sands. The Jubilee field straddles the West Cape Three Points and Deepwater Tano licences.

In July 2009, the Minister of Energy approved the Phase 1 Plan of Development which included the use of an FPSO with a facility capacity of 120,000 bopd. In December 2010, the field came on-stream.

The Jubilee Phase 1A development project, designed to increase production and recover additional reserves, was approved by the Government of Ghana in January 2012. Phase 1A consisted of eight additional wells which included five producers and three water injectors. 

An issue with the turret bearing of the Jubilee FPSO Kwame Nkrumah was identified in February 2016. This resulted in the need to implement new operating and offtake procedures, utilising a dynamically positioned shuttle tanker and a storage vessel.

As announced in June 2016, Tullow and its Partners established that the long-term solution is to convert the FPSO to a permanently spread moored facility. The Jubilee turret remediation work is progressing as planned and the FPSO was spread-moored on its current heading in February 2017. The capital costs associated with the remediation works are being covered by the Joint Venture Hull and Machinery insurance policy.

The next phase of the project will involve stabilisation of the turret bearing and a shut-down of 4-6 weeks is planned for the first quarter of 2018. The following phase to rotate the FPSO to its permanent heading and to carry out the final spread-mooring will take place around the end of 2018 and is expected to require a shut-down of approximately three weeks. Work is also continuing on the plan for the installation of a deep-water offloading system which would take place in 2019 and result in minimal interruption to production.

Tullow expects net 2017 production from the Jubilee field to average 31,600 bopd. This increases to 38,400 bopd, after adding the equivalent average annualised net production of around 6,800 bopd from Tullow’s corporate Business Interruption insurance cover, which is expected to continue to payout in respect of lost production associated to the turret remediation works. 

In December 2015, Tullow submitted the Greater Jubilee Full Field Development Plan to the Government of Ghana. This project, to extend field production and increase commercial reserves, was redesigned given the current oil price environment, to reduce the overall capital requirement and allow flexibility on the timing of capital investment. Approval of the Greater Jubilee Full Field Development Plan by the Government of Ghana was given in October 2017, permitting infill drilling to commence on the Jubilee field and subsequent development of the Mahogany and Teak fields.
