Tullow oil to optimise well production offshore Ghana

TEN field's total production count for 2025 is 16.0 kbopd.

With all reservoir and operations risks for 2026 considered, Tullow Oil is aiming an average production rate of 34-42 kboepd, including 6 kboepd of gas

In 2025, Ntomme and Enyenra performance from TEN led the field's total production count at 16.0 kbopd, while the exit rate from Jubilee stood at 57 kbopd.

The company will be deploying riser system and riser-base gas lift for well production management activities, and waterflood and fluid lift optimisation. These, along with the support of high-uptime FPSO, five planned Jubilee wells (four producers and one water injector) are expected onstream this year. The J75-P, for instance -- where a rig has been active for drilling -- has recorded three good reservoir intervals.

The recently completed J74-P well is already onstream since January, revealing 50 meters of net pay while generating an initial gross production through the wellbore at 13 kbopd.

The well management measures align with findings from 4D seismic and Ocean Bottom Node seismic surveys to leverage significant reservoir information extracted.

Tullow has made a strategic investment to acquire the TEN FPSO as it will simplify operational synergies between the TEN and Jubilee fields, maximising output in the long term with minimal expenses. The company has already secured 10-year and 14-year-long ratifications on the West Cape Three Points and Deep Water Tano Petroleum Agreements.

Ian Perks, chief executive officer, Tullow Oil Plc, said, “2025 has been a year of disciplined execution across the business. This includes strong operational momentum which continues with excellent results from the latest Jubilee well and a further five wells due onstream this year to support our production targets. We have achieved significant cost reductions and completed the sale of non-core assets in our ongoing efforts to streamline our portfolio and strengthen our financial position.

“However our 2025 full year free cashflow was negatively impacted by the commodity price environment towards the end of the year and delays in receipt of Government of Ghana receivables and the second instalment of proceeds from the Kenya disposal.

“The refinancing transaction we have announced today enables us to focus on delivering our near-term priorities, which include driving further cost efficiencies, improving cashflow management and optimising our production."

ABL to deliver marine support for Kamose field

The campaign will also cover drilling three wells.

Energy and marine consultancy, ABL, will be delivering marine warranty survey services to support the offshore construction for the Phase 4 development of the Kamose offshore gas field development in the Mediterranean Sea for North Sinai Petroleum Company (NOSPCO)

The Kamose Phase 4 development, which is located at the Eastern flank of the Nile Delta, will advance the construction and installation of three new offshore production platforms monopods, named Hoor-1&2, KSE-1 and Snefru-1.

The campaign will also cover drilling three wells via wellhead platforms and connecting its production by installing an 11 km flowline to the existing production network. The infrastructure will be connected to the main offshore pipeline and integrated with the mobile offshore production unit (MOPU) already in place at the Kamose field.

ABL’s scope of work includes technical review and approval of all project documentation, procedures, drawings and calculations. It will also deliver marine assurance and risk services for the proposed fleet, including DP (dynamic positioning) trials and consulting where relevant.

“ABL Egypt brings together local competence, marine experience, engineering expertise and expert process safety engineering to provide a comprehensive offering that will support the safe and optimised delivery of T&I operations for Kamose Phase 4. We look forward to supporting NOPSCO on this important development for Egyptian offshore gas,” said Tamer Gamil, country manager, ABL Egypt.

Perenco Congo installs new-generation Kombi 2 platform

Kombi 2 is designed to meet global sustainability standards.

Perenco Congo has installed the new Kombi 2 platform with connection work currently underway on the Kombi-Likalala-Libondo II (KLL II) field, before commissioning begins early March

This marks the first redevelopment move in more than 20 years since the drilling of its last well.

The field's future performance will stand secured from Kombi 2's new-generation infrastructure that ensures improved water and effluent treatment and increased associated gas recovery. On top of that, two gas turbines will generate 8 MW of electricity for greater energy autonomy for operations.

Designed to meet global sustainability standards, the six-well drilling campaign starting this year will involve production optimisation, enhanced field recovery, and field-life extension work, all of which will be supported by the forward-looking Kombi 2 platform.

Considering it a historic field, Perenco Congo has invested more than US$200mn with a long-term strategy in the region. “This project is a concrete example of Perenco's commitment to investing in high-performance, responsible, and value-creating infrastructure that promotes the sustainable development of national resources,” said Gregoire de Courcelles, managing director of Perenco Congo.

Akrake prepares for production offshore Benin

A down-hole electrical submersible pump will be installed.

The company is now working on completion activities to make the well production-ready by early February. It has been designed to drain the western section of the Seme Field from the H6 reservoir.

The well will be screened covering the reservoir sandstone formation, and a down-hole electrical submersible pump (ESP) will be installed.

Alongside, installation of the mobile offshore production unit (MOPU), Stella Energy 1, and the floating storage & offloading unit (FSO), Kristina, are in the final stages.

The MOPU installation activities which involved flowlines connection set-ups and other technical addressing were responsible for some delays in production start-up.

Akrake Petroleum's Seme Field redevelopment campaign involves a 100-day three-well work-programme. It includes the drilling of two horizontal production wells in the H6 formation (previously developed), as well as a deeper vertical appraisal well to gather data from the H7 and H8 reservoirs, to facilitate the potential advancement to Phase 2 of the development.

FSO arrives to support production start-up in Seme offshore Benin

The mooring system for the FSO is currently being installed.

The three-well drilling campaign by Rex International Holding Limited in the Seme Field, Benin, goes on as the floating storage & offloading (FSO) unit has arrived and is at the anchorage

The mooring system is currently being installed and will be hooked up with a flowline to the mobile offshore production unit (MOPU). Before the MOPU arrives this month, the team is working on remedial actions to address certain technical issues that the campaign had been facing. While this may lead to some delays, production start-up is being targeted by December end.

Akrake Petroleum Benin SA holds a 76% interest in the Seme Field in Block 1, Benin, and is the operator. It is a wholly-owned subsidiary of Lime Petroleum Holding AS, an 89.74 per cent subsidiary of Rex.

The campaign involves a 100-day three-well work-programme to redevelop the Seme Field. This will see the drilling of two horizontal production wells in the H6 formation (previously developed), as well as a deeper vertical appraisal well to gather data from the H7 and H8 reservoirs, to facilitate the potential advancement to Phase 2 of the development.

The production start-up and optimisation in the Seme Field will be backed by additional data on the subsurface alongside the existing 3D seismic that has been reprocessed by the team.
