Tullow Ghana Limited plans to bring four additional wells online at the Jubilee field offshore Ghana over the coming months, following the start-up of two wells already delivered in 2026.
The company said six Jubilee wells are scheduled to come on stream this year, consisting of five producers and one water injector. J74-P and J75-P are already producing, while three further producer wells are expected to start up in June and July. The remaining water injector is planned for September.
Reservoir management remains a key focus. Tullow Ghana Limited is optimizing waterflood operations to support pressure levels and improve oil recovery. Production is also being managed through the riser system, with riser-based gas lift used to sustain output and offset natural field decline.
Ghana operations maintained strong reliability in 2025, with average facility uptime across the FPSOs at 97%. Combined average net oil production stood at about 32.5 kbopd in 2025, rising to 35.4 kbopd in the first quarter of 2026.
At Jubilee, gross oil production averaged 60.9 kbopd in 2025, or 23.7 kbopd net. Output was affected in the first half of the year by higher-than-expected water cut from some wells, which disrupted riser stability on the eastern side of the field. Riser-based gas lift was introduced there, restoring and stabilizing production in June 2025.
A similar gas lift system for Jubilee’s western side has been approved and is expected to support production once fully implemented in 2027. The company said cumulative voidage replacement increased to 107% in the second half of 2025 after seawater lift system issues were resolved.
At the TEN fields, gross oil production averaged 16.0 kbopd in 2025, or 8.8 kbopd net, supported by well zonal optimization at Enyenra and water injection optimization. Net gas production in Ghana averaged 6.8 kboepd in 2025.
The FPSO TEN flare tip was replaced in May 2025, cutting routine flaring by about 50% from July 2025. Tullow Oil also expects more than 10 mmboe of additional net 2P reserves after the extension of its Ghana petroleum agreements to 2040.
Under the arrangement, Ghana National Petroleum Corporation will receive a further 10% field share from 20 July 2036, with joint venture partners reducing their stakes on a pro rata basis.
Following the purchase of FPSO TEN, Tullow Oil expects to reduce costs by removing the annual lease payment and capturing synergies with the Jubilee FPSO. The company also sees potential in 4D seismic and ocean bottom node data to support future drilling in Jubilee and TEN.
Chief Executive Officer Ian Perks said 2026 had started strongly, supported by early results from the Ghana drilling campaign. He added that the TEN FPSO purchase, extended petroleum agreements, and higher oil prices had strengthened the company’s growth platform.
