Four Projects, Four Paths to FID: MSGBC Basin's Next Wave of Development Decisions
)
The MSGBC basin's first generation of producing assets has demonstrated the region's ability to deliver world-class energy projects, with attention now turning to the next wave of developments. Across Mauritania and Senegal, four major projects are progressing toward final investment decisions (FIDs), each with its own resource base, development model and investment requirements. At MSGBC Oil, Gas & Power 2026, the session "From Discovery to Development: Projects Moving Toward FID" will explore the progress, challenges and commercial pathways shaping these flagship developments.
Sangomar Phase 2 would expand Senegal's flagship offshore oil development, which has sustained production at its 100,000-barrel-per-day nameplate capacity since shortly after first oil in June 2024. Operator Woodside Energy and national oil company Petrosen are in active discussions regarding a second phase that could unlock an additional 250 million barrels of recoverable oil. The negotiations are expected to assess Phase 1 production performance alongside the fiscal and contractual framework for the expansion. As a confirmed participant at MSGBC 2026, Woodside is expected to provide valuable insight into the project's next phase.
GTA Phase 2 would expand the Greater Tortue Ahmeyim LNG project, operated by bp in partnership with Petrosen, SMH and Kosmos Energy. The partners are evaluating a gravity-based structure (GBS) capable of producing between 2.5 million and 3 million tons of LNG annually, integrated with existing Phase 1 infrastructure. The project remains under evaluation, with future development expected to be guided by Phase 1 performance and ongoing commercial discussions between the project partners and the governments of Mauritania and Senegal.
Yakaar-Teranga, one of West Africa's largest gas discoveries with an estimated 25 Tcf of recoverable resources, is now wholly owned by Petrosen following Kosmos Energy's exit in April 2026. The Senegalese government is repositioning the project as a domestic gas development, with Petrosen targeting an FID by the end of 2026. Estimated to require approximately $7.5 billion in investment, the project is expected to drive discussions around financing structures, strategic partnerships and domestic gas commercialization.
BirAllah, Mauritania's estimated 80 Tcf gas resource in Block C8, is also entering a new phase. Following the departures of bp and TotalEnergies, state-owned SMH has assumed the operatorship while the government seeks a new strategic partner to advance the project. With first gas targeted for 2030 and reports indicating Energean is evaluating a potential entry, BirAllah reflects Mauritania's growing focus on gas development to support domestic power generation alongside longer-term commercialization opportunities.
Although each project is following a different development pathway, all face critical technical, commercial and financing milestones before reaching FID. Bringing together operators, government representatives and investors, the MSGBC 2026 session will provide timely insight into the investment strategies, partnership models and policy frameworks shaping the basin's next generation of energy projects.
