Key statistics

The start of 2011 saw the first lifting of Jubilee crude oil from the FPSO Kwame Nkrumah and since then, over 55 million barrels of oil have been produced and safely exported. Following the strong operating performance of the Kwame Nkrumah FPSO, Tullow, on behalf of the Jubilee Partners, acquired the FPSO from Modec on 29 December 2011.  This acquisition will enable the Jubilee Partners to maximise the FPSO’s commercial value and operational efficiency whilst Modec will continue to provide operations and maintenance services.

The Jubilee Phase 1 development was completed in October 2011 when the last of the initial 17 wells were drilled, completed and brought on stream. Also at this time, the water injection design capacity for the FPSO was reached, with rates over 235,000 bwpd being injected into the reservoirs and pressure support being seen across the field. By the end of 2011, gas re-injection reached 80 mmscfd and gas flaring was reduced to minimal levels. 

In 2011, gross production from the Jubilee field averaged 66,000 bopd, reaching 88,000 bopd before declining to approximately 70,000 bopd at the end of the year. However, production from the field was below expectations due to reduced productivity in a number of wells. The issue is not expected to impact the level of field reserves or resources and a remedial work programme was successfully carried out in 2012 to regain well productivity. This work initially involved the sidetracking of the J-07 production well using a new completion design which is now on-stream. However, acid stimulations was identified as the optimum solution to return the wells to their original productivity and a number of these were successful completed in 2012 with production in early 2013 at around 110,000 bopd.

Following Government approval at the beginning of 2012, the Phase 1A development project is progressing as planned with initial production wells now onstream. All of the wells have encountered good quality reservoir on prognosis. This Phase of the development will be completed in the third quarter of 2013 and following some gas compression work to be carried out on the FPSO during the same quarter, it is expected that the field will exit the year producing in excess of 120,000 bopd.

In the second half of 2012, the Tweneboa-Enyenra-Ntomme (TEN) project made good progress and Tullow and partners submitted the Plan of Development to the Minister of Energy in early November 2012.
