An additional production well on the Tweneboa-Enyenra-Ntomme (TEN) field, which is being drilled, is expected to be completed and tied-in by the end of the first quarter of 2020.

This is according to the 2020 projections of Tullow Oil Plc.

The most recent activities engaged by the company include the tie-in of the J-54 water injector well at the Jubilee field and planning for a maintenance period at the end of January to increase gas processing capacity.

Tullow expects to continue to use the Maersk Venturer rig across both the TEN and Jubilee fields in 2020. The well program is being developed with the Joint Venture Partners and will be finalized by the end of the year.

Information available indicates that Tullow and its Joint Venture Partners in Ghana continue to assess the appropriate investment program in 2020 to improve the performance of the fields and their facilities.

This includes re-assessing both the infill drilling program and future development plans to ensure that the significant remaining reserves and resources at Jubilee and TEN are produced in the most cost-effective and efficient manner in 2020 and beyond.

2019 performance

Tweneboa-Enyenra-Ntomme

At TEN, gross full year 2019 production is estimated to be around 62,000 bopd. During 2019, production had been impacted by the suspension of the EN14-P well and therefore production was drawn on fewer wells than planned.

Jubilee

At Jubilee, gross full year 2019 production has been estimated to be around 89,000 bopd (c.31,500 bopd net). The lower than forecast full year outcome is predominantly due to topside issues which have constrained water injection and gas handling.

Water injection was returned to full capacity at the end of November, whereas enhancements to the gas handling system are planned for early 2020 to increase gas throughput capacity which will reduce gas management constraints.
