The Jubilee field is located 60km offshore, between the Deepwater Tano and West Cape Three Points blocks in Ghana.
It was discovered in 2007 and developed by Tullow Oil.
Equity partners of the Deepwater Tano block are Tullow with 49.95%, Kosmos with 18%, Anadarko with 18%, Sabre Oil & Gas with 4.05%, and Ghana National Petroleum Corporation (GNPC) with 10%.
West Cape Three Points is held by Tullow with 22.9%, Kosmos with 30.88%, Anadarko with 30.88%, Sabre Oil & Gas with 1.85%, GNPC with 10%, and EO Group with 3.5%.
The Jubilee appraisal and development programme began at the end of 2008 and the Odum, Mahogany-2, Heydua-2 and Mahogany-3 wells were drilled.
Parallel to the appraisal drilling programme, phase I development of the core field has progressed at a rapid pace since July 2008. Tullow is the operator and Kosmos Energy is the technical operator of the phase I development plan.
The tanker vessel Ohdoh was converted for the Jubilee field and christened the floating, production, storage and offloading (FPSO) vessel Kwame Nkrumah MV21.
It began production in 2010 and produces oil. The total proven reserves of the Jubilee oil field are around 2 billion barrels (268×106tonnes), and production is centered around 85,000 barrels per day (13,500 m3/d).
Tullow Oil failed to meet production targets at the Jubilee oilfield at the end of 2012, causing problems for the firm and the Ghanaian government. The declining productivity led to declining revenues for the government who had budgeted for oil revenue of more than $650 million. The corresponding shortfall was more than $410 million. The oil firm blamed the decline on “sand contamination of the flowlines that carry the oil from the underwater wells” to the storage facility on the surface.
