Equinor Enters Angola’s Offshore Block 16/21 With 30% Stake in Exploration Deal
Norwegian energy company Equinor has acquired a 30% participating interest in Angola’s offshore Block 16/21, marking its official entry into the exploration asset through a partnership with operator TotalEnergies.
The agreement was signed on June 11, 2026, in the presence of the National Oil, Gas & Biofuels Agency (ANPG).
The transaction forms part of ongoing efforts to attract international investment into Angola’s upstream oil and gas sector.
Located in the Lower Congo Basin, Block 16/21 is considered highly prospective due to its proximity to Block 17, one of Angola’s most productive offshore areas, which hosts major developments such as CLOV and Dalia.
The block also contains two previously discovered fields Bengo, discovered in 1994, and Longo, discovered in 1995.
Exploration potential is further supported by an extensive dataset of 3,684 kilometres of seismic coverage, which was reprocessed by TGS in 2025 to improve subsurface imaging and evaluation.
According to the ANPG, the agreement between TotalEnergies and Equinor reflects a shared strategy to advance exploration and unlock new offshore oil and gas resources in Angola’s deepwater basins.
The transaction remains subject to final regulatory approval before it becomes fully effective.
Equinor’s entry into Block 16/21 strengthens its footprint in West African upstream markets and underscores continued international interest in Angola’s mature but still highly prospective offshore geology.
