Recoverable barrels of oil from a well in the Bourdon prospect in the Dussafu Licence offshore Gabon have successfully surpassed millions following drilling 

The second sidetrack DBM-1 ST2 well that has been drilled by the Norve jack-up rig for BW Energy has revealed 56 million barrels oil estimates in place. Of these, approximately 25 million barrels are considered recoverable. 

Confirming the substantial oil discovery with good reservoir and fluid quality, Carl K Arnet, CEO of BW Energy, said, “The appraisal well confirms the potential for establishing a new development cluster with a production facility following the MaBoMo blueprint. We expect at least four producing wells.” 

“We continue to successfully expand the Dussafu reserve base which, together with multiple additional prospects yet to be drilled, will support long-term production and value-creation in Gabon.”

Surpassing expectations

Initial data shows that oil from Bourdon field has the lowest viscosity of the Dussafu discoveries measuring an average of 3.5 centipoise (cp), compared to 5 cp and 7 cp for the Hibiscus / Tortue and Ruche fields, respectively.

Evaluation of logging data and formation pressure measurements confirm approximately 11.2 metres of pay in an overall hydrocarbon column of 35.2 metres in the Gamba formation, drilled to a depth of 4,731 metres.

Bourdon is located approximately 15 kilometres west of FPSO BW Adolo and 7.5 kilometres southeast of the MaBoMo facility. The discovery will enable the Company to book additional reserves not included in its 2024 Statement of Reserves.

Reconnaissance Energy Africa Ltd has announced a drilling update on Prospect I

Prospect I is located onshore Namibia in Petroleum Exploration Licence 073 (PEL73) and is the company's largest prospect to be drilled so far. It is targeting 365 million barrels of unrisked and 32 million barrels of risked prospective light/medium oil resources , or 1.9 trillion cu/ft of unrisked and 140 bn cu/ft of risked prospective natural gas resources, on a 100% working interest basis, based on the most recent prospective resources report prepared by Netherland, Sewell, & Associates, Inc. (NSAI), an independent qualified reserves evaluator. Prospect I is noted as location 63 in the NSAI report.

Brian Reinsborough, president and CEO of ReconAfrica said, "We are excited to be making great progress ahead of drilling one of the company's largest and most attractive prospects. The results of the Naingopo exploration well announced in January 2025 increased our confidence in the potential for Prospect I. We remain on track to spud the well this quarter and are looking forward to unlocking the significant potential of the Damara Fold Belt."

Pre-construction activities are continuing on schedule and the pre-drill evaluation is complete. The drilling schematic demonstrates that we are targeting a drilling depth of 3,800 metres with the potential to drill deeper, as we did for the Naingopo exploration well. The thickness of the Otavi section is expected to be approximately 1,500 metres to 1,800 metres depending on how deep we are able to drill. The learnings from the Naingopo exploration well have improved our understanding of the Damara Fold Belt with respect to our geologic model including time and depth migration for the Mulden and Otavi sections. This is the same reservoir where we encountered over 50 metres of reservoir quality carbonates and encountered oil shows in the Naingopo well.

Valaris Limited has been awarded a two-year contract offshore West Africa for drillship VALARIS DS-10

The US$352mn contract is expected to commence late in the second quarter or in the third quarter 2026. The total contract value does not include the provision of additional services, but two unpriced options, each with a duration of one year.

More long-term contracts

President and chief executive officer, Anton Dibowitz, said, “This contract award is a testament to the safety and operational performance of VALARIS DS-10 and its crews, which have an excellent track record of successfully executing clients’ well programmes offshore West Africa. This contract increases our backlog by approximately US$350mn and supports our future earnings and cash flow, and we remain focused on securing additional attractive long-term contracts for our high-specification assets.” 

West Africa has seen enhanced rig activity, with Shelf Drilling and Borr Drilling also announcing contracts since late last year. 

Vitol has been one of the recent entrants to West Africa, acquiring interests worth approximately US$1.65bn.
