A Tullow report sighted here on Thursday indicated that the production challenges on Ghana’s Jubilee field were not over yet as solutions could stretch into 2018.
According to the report, a Tullow Trading Update on its Ghana website, the Jubilee Floating Production, Storage and Offloading ( FPSO) Kwame Nkrumah faces extended shutdown for mooring realignment.
The interim spread mooring of the Jubilee FPSO offshore Ghana was completed in February as part of the Spread Mooring arrangements decided upon last year after partners identified issues with the turret bearings.
The report said operators were in discussions with the government of Ghana on stabilization procedures for the turret and the final heading of the FPSO, with Gross production averaging 82.500 barrels of oil per day (82,500 BOPD) on the Jubilee field during the first quarter of 2017.
“Tullow expects final decisions to be made around the middle of the year with work to be undertaken in the second half of 2017. It is anticipated that a facility shutdown of up to 12 weeks may be required during 2017.
“However, work is ongoing to look at ways to optimize and reduce shutdown periods,” the report added.
Most of the positive economic performance projections on Ghana for 2017 were hinged on better oil and gas production from Jubilee and the Tweneboa-Enyenra-Ntomme (TEN) fields as well as the expected commencement of gas production from the Sankofa field operated by ENI and Vitol later this year.
The Jubilee partners have also been working at the full field development at Jubilee to ensure a sustained full field production, the report said, adding that work by government of Ghana and the partners to update the Greater Jubilee Full Field Development Plan (GJFFD) was progressing.
For this, the operators said a 4D seismic survey was completed in the first quarter of the year and data acquired will be used to optimize the location of GJFFD wells and to assist with ongoing reservoir management.
“The JV Partners remain on track to re-submit the plan around the middle of the year, with approval expected in the second half of the year allowing drilling to commence in early 2018,” according to Tullow’s statement.
Production on the TEN field on the other hand met projections of 50.000 bopd in the first quarter of 2017 with Tullow’s annual production forecast unchanged at around 50,000 bopd.
Final ruling on the Ghana-Cote d’Ivoire Maritime Boundary dispute being heard at the International Tribunal on the Law of the Sea (ITLOS) in Hamburg, Germany, is expected in September, which would decide whether Ghana or Cote d’Ivoire actually owned parts or the entire TEN field.
“This has been an exceptionally busy few months for Tullow and we have made good progress on the Jubilee Turret Remediation Project and optimizing production from the TEN field,” Aidan Heavey, who is set to hand over the role of Group Chief Executive Officer (CEO) to Paul McDade, said. Enditem
