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 the FPSO Kwame Nkrumah. 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. 

Turret remediation project

The Turret Remediation Project is close to completion. This pioneering and unique project, which included the first ever remediation of this type at sea, required the FPSO Kwame Nkrumah to be shut down twice in the first half of 2018 for work to stabilise the turret bearing for periods of 19 days and 21 days respectively. In December 2018, the FPSO was successfully rotated to its new heading of 205 degrees and subsequently spread-moored.  

The JV Partners have also agreed to install a Catenary Anchor Leg Mooring (CALM) buoy for offtake from the FPSO and a contract award has been made. The installation of the CALM buoy is likely to take place in 2020 and is not expected to affect production.

Production performance

 At Jubilee, gross full year 2019 production is forecast to be around 89,000 bopd (c.31,400 bopd net). Production-equivalent insurance payments ended in May 2019 and, following a final reconciliation, the average for the full year is 2,000 bopd net.      

Greater Jubilee Full Field Development Plan

The Government of Ghana approved the Greater Jubilee Full Field Development Plan in October 2017, allowing Tullow and its Joint Venture Partners to prepare for a multi-year incremental drilling programme to maximise and sustain oil production and gas export. 

Tullow expects to continue to use the Maersk Venturer rig across both the TEN and Jubilee fields in 2020. The well programme is being developed with the Joint Venture Partners and will be finalised by the end of the year.
