Norwegian energy company Equinor has acquired a 30 percent participating interest in Angola’s offshore Block 16/21, formally entering a new exploration asset in partnership with operator TotalEnergies. The agreement was signed on 11 June 2026 in the presence of Angola’s National Oil, Gas and Biofuels Agency (ANPG), forming part of a sustained push to attract fresh international capital into Angola’s upstream sector.
Block 16/21 is located in the prolific Lower Congo Basin and is considered highly prospective due to its proximity to Block 17 — one of Angola’s most productive offshore areas, home to landmark developments including CLOV and Dalia. The block also contains two previously identified oil discoveries: the Bengo field, found in 1994, and the Longo field, found in 1995, both of which remain available for appraisal and potential development.
Exploration confidence in the block is supported by an extensive seismic dataset covering 3,684 kilometres, which was fully reprocessed by TGS in 2025 using advanced subsurface imaging techniques to sharpen evaluation of the block’s structural and stratigraphic targets.
According to the ANPG, the partnership between TotalEnergies and Equinor reflects a shared strategy to advance exploration and unlock new deepwater resources in Angola’s mature but still highly prospective basins. The transaction remains subject to final regulatory approval before it becomes fully effective.
Equinor’s entry into Block 16/21 deepens its commitment to West African upstream markets and reinforces sustained international interest in Angola’s offshore geology at a time when the country is actively courting new investment to sustain long-term production.
