The Aseng Gas Monetisation Project offshore Equatorial Guinea will undergo subsea installation by Subsea7, which has received a significant contract by Noble Energy EG Ltd (a Chevron Company)

Subsea7 will be establishing a single-well tieback for the project, connecting Aseng field to the existing Alen platform. It will transport and install approximately 19 kilometres of rigid production flowline and 20 kilometres of umbilicals, along with associated subsea structures and tie-ins in water depths of 800 metres.

Project management and engineering will commence immediately and will be managed from Subsea7’s Paris office, with additional support from teams in Lisbon and Equatorial Guinea. Offshore activities are expected to begin in 2026.

David Bertin, Senior Vice President for Subsea7’s Global Projects Centre East, said, “This award represents an important milestone in our ongoing global relationship with Chevron. Subsea7 has operated in Equatorial Guinea for nearly two decades, supporting offshore construction and inspection, maintenance and repair activities. We look forward to continuing our collaboration with Chevron on the Aseng Gas Monetisation Project, continuing to deliver safe, high-quality offshore installation services in West Africa.”

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.
