LONDON – Tullow Oil forecasts average oil production of more than 100,000 bbl/d later this year from the deepwater Jubilee Field offshore Ghana.
Up to six wells should come onstream from mid-year onward.
In second-half 2022, two wells were drilled in the Jubilee South East area and a third is currently drilling. Some of the deeper reservoirs penetrated have encountered additional resources that could be developed in future.
The new wells will start up following installation and tie-in to the Jubilee South East project subsea infrastructure.
Last July, Tullow assumed operatorship of the Jubilee FPSO. Under its management, the company said FPSO uptime averaged c.99% in the second half of 2022, compared to c.95% in the first half.
Operations and maintenance (O&M) costs were c.30% lower in the second half of the year.

At the nearby TEN fields, production this year should level off at about 20,000 bbl/d. Last September Tullow brought online a new producer well at Enyenra, and at Ntomme, pressure support from gas and water injection led to steady production.
However, two wells drilled in the Ntomme riser base area did not encounter economic resources and will not be completed this year as planned.
Tullow’s short-term priorities for TEN include improving gas handling on the FPSO during a maintenance shutdown scheduled for the third quarter. This should also lead to reduced flaring and increased gas injection to support oil production.
Longer term, the plan is to monetize TEN’s remaining resources through infill drilling, particularly on Ntomme; phased development of new areas near existing infrastructure; and development of the gas resources and drilling of prospective resources.
Tullow expects to submit a plan of development to the government of Ghana later this year.
