Chevron's Strategic Expansion into Guinea-Bissau

Chevron is expanding its exploration activities in West Africa, designating the region as a key strategic focus. This expansion is marked by an agreement to explore two deepwater offshore blocks, 5B and 6B, located in Guinea-Bissau's MSGBC basin. This basin, encompassing Mauritania, Senegal, Gambia, Guinea-Bissau, and Guinea-Conakry, has attracted significant international attention following major oil and gas discoveries like Sangomar and Greater Tortue Ahmeyim.

Operational Details and Partnership

Under the agreement, Chevron's local subsidiary will operate both blocks with a 90% working interest. The remaining 10% interest will be held by Petroguin, Guinea-Bissau's national oil company. The blocks are situated in deep to ultra-deepwater zones. The initial phase of work will involve Chevron interpreting existing 2D and 3D seismic data to assess potential prospects. While these initial studies are focused on seismic interpretation, specific timelines for drilling activities have not yet been established.

Strategic Alignment and Regional Context

This entry into Guinea-Bissau aligns with Chevron's global strategy of pursuing high-return conventional exploration opportunities. A company executive emphasized that West Africa remains a strategic region and that Chevron continues to seek additional high-quality acreage across the basin, with a specific focus on oil opportunities. This move reinforces Chevron's growing interest in the MSGBC basin, one of Africa's most active emerging exploration frontiers, and strengthens its regional portfolio alongside its established operations in countries like Nigeria and Angola.
