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 the Mauritania-Senegal-Gambia-Bissau-Conakry (MSGBC) basin of Guinea-Bissau. This basin has attracted significant international attention following major oil and gas discoveries such as Sangomar and Greater Tortue Ahmeyim (GTA).

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 evaluate the potential of the prospects. While these initial studies are focused on seismic interpretation, specific timelines for drilling activities have not yet been established.

Strategic Rationale and Regional Context

This entry into Guinea-Bissau aligns with Chevron's global strategy of pursuing high-return conventional exploration opportunities. The company has stated that West Africa remains a strategic region and that it continues to seek additional high-quality acreage across the basin, with a particular focus on oil opportunities. This move strengthens Chevron's regional portfolio, complementing its established operations in other West African nations such as Nigeria and Angola, and underscores its continued interest in the MSGBC basin as one of Africa's most active emerging frontiers.
