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. 

Turret remediation project

An issue with the turret bearing of the Jubilee FPSO Kwame Nkrumah was identified in February 2016.  In June 2016, Tullow and its Partners established that the long-term solution was to convert the FPSO to a permanently spread moored facility. The FPSO was spread-moored on its current heading in February 2017. 

The next phase of the project to stabilise of the turret bearing was completed in the first half of 2018 and the final task to rotate the FPSO to its permanent heading and to carry out the final spread-mooring will take place around the end of 2018, with minimal impact on production. 

Production performance

Tullow forecasts full year gross production from the Jubilee field to average around 78,100 bopd (net: 27,700 bopd), up from 75,800 bopd gross (net: 26,900 bopd) previously guided. Tullow expects net production-equivalent insurance payments for the full year to be around 8,700 bopd (previously 10,200 bopd). Accordingly, full year net production guidance from Jubilee, including production-equivalent insurance payments, is now around 36,400 bopd.

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. 

In the first half of 2018, two new Jubilee production wells, J51-P and J53-P, were drilled by the Maersk Venturer as part of the current drilling campaign. These wells have successfully met all pre-drill expectations and will be completed and brought on stream during the third and fourth quarters of 2018. A previously drilled Jubilee water injection well will also be tied-in. In 2019, the Group intends to drill further wells to sustain and maximise plateau production.
