New log analysis from latest rock data has refined all previously disclosed results.

With regulatory permits for production testing secured and production liner procured from North America, work crews from Reconnaissance Energy Africa have prepared the Kavango West 1X discovery well in Namibia for testing operations 

Equipment and services will be delivered on site by contracts with Halliburton and SLB, while local suppliers have been engaged in multiple support capacities.

New log analysis from latest rock data has refined all previously disclosed results. The current petrophysical analysis indicates 75 metres (246 feet) of net hydrocarbon pay in the Huttenberg formation, an increase over the previously disclosed 64 metres (210 feet).

ReconAfrica, which is the operator of Kavango West, will be conducting production testing across six optimized zones, three of which are in the Huttenberg formation and three in the deeper Elandshoek formation. A total of 345 metres (1,132 feet) of prospective interval will be isolated and perforated for testing. 

In the shallow waters of Gabon, the company is currently reprocessing 3D seismic data across focused regions for appraisal prospects within the 1,214 sq km-long Ngulu block, including the Loba discovery. 

This strategic block is located on trend to several sizable producing oil fields. The key aspects of the Ngulu block include the Loba oil discovery and over 28 seismically identified prospects in the pre- and post-salt plays. 

The company will be conducting testing and commissioning activities.

Rex-subsidiary, Lime Petroleum Holding AS, has completed hooking up the mobile offshore production unit (MOPU) and the floating storage and offloading unit (FSO) on the Seme Field in Benin

The FSO Kristina has been anchored in place as well. A flow-line has been laid from the Stella Energy 1 MOPU to the FSO. Commissioning of the production system is well underway, with oil now flowing into the FSO. 

This comes as part of 100-day three-well work-programme to redevelop the Seme Field. The campaign 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.

With all connections now in place, the company will be further conducting testing and commissioning activities to attain production optimisation and start regular production. 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. 

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.

Corcel Plc has reported excellent data quality from initial internal review following the acquisition of 2D seismic at the operated KON-16 Block, within the Kwanza Basin onshore Angola 

"The project was executed without incident, to a very high standard, and the initial results are incredibly encouraging," said Richard Lane, Corcel's chief operating officer while calling the programme a "milestone" as it came as part of the company's fist operated exploration and production project. 

Delivered on schedule, the 326-line kms of high resolution 2D seismic data provided clear imaging of key pre‑salt structures, implying an opportunity to de-risk several pre-salt and post-salt zones before initiating drilling within KON-16. Prospect maturation and drilling preparation will be determined by results from the year-long seismic processing that has been specifically designed with the region's high-graded pre salt indications in mind.

Corcel's aim to crack KON-16's complex pre-salt plays is exactly where DUG Technology's imaging expertise lies in. The geophysical processing specialist will be undertaking the project, ensuring the KON‑16 dataset is processed to the highest technical standard.

The acquisition programme was largely supported by BGP INC, China National Petroleum Corporation and its local subsidiary.

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."
