LONDON– Tullow Oil says the first planned maintenance shutdown on the Jubilee FPSO Kwame Nkrumah offshore Ghana has been completed ahead of schedule.
Current focus is on optimizing the vessel’s gas handling. A third gas injection well has come online, and gas export infrastructure is expected to be operational during the second half of 2014.
Phase 1A development drilling has boosted well capacity to more than 150,000 b/d of oil. Tullow expects Jubilee to produce more than 120,000 b/d by year-end, subject to completion of the gas optimization work.
The recently drilled Akasa-2A appraisal well successfully tested the downdip extent of the Akasa accumulation, and the partners continue to study development options for Mahogany, Teak, and Akasa in the West Cape Three Points license.
In the adjoining Deep Tano license, Tullow says it has awarded all main contracts for theTweneboa, Enyenra, and Ntomme (TEN) development project. Last month, the Centennial Jewel trading tanker arrived at the Jurong Shipyard in Singapore, where it will be converted to the TEN FPSO.
At the end of August, the company started drilling the Frégate exploratory well in the C-7 license offshore Mauritania and this is expected to reach total depth in December. The rig will then likely transfer to the C10 and C6 blocks to drill the Tapendar and Sidewinder prospects.
Following last November’s declaration of commerciality for the offshoreBanda field, the Mauritanian government has approved a development plan that involves supplying gas from the field to a new local power station. Negotiations are under way with the World Bank on commercial contracts to assist the full project sanction process.
In Côte d’Ivoire offshore block CI-103, the Paon-2A appraisal well started drilling on Oct. 24.
Offshore Guinea, a 4,000-sq km (1,544-sq mi) 3D survey has been acquired and the Fatala (ex-Eos) prospect will be drilled early next year.
Off Gabon, Tullow’s Crabe exploration well (KCM-1) in the Kiarsseny Marine license has been P&A’d as a dry hole. The rig has since moved to drill the Perroquet well (KPM-1) in the same block.
Across the Atlantic, the Shell-led consortium’s fourth and final well in its present drilling campaign offshore French Guiana,GM-ES-5, has been drilled into the water leg of the Zaedyus-1 oil pool to determine the oil/water contact. The well has reached total depth and evaluation continues.
Offshore neighboring Suriname, Tullow has acquired a 30% equity stake in block 31, and has reached agreement with Repsol to take a 30% interest in the newly defined Kanuku block offshore Guyana, pending government approval.
