Offshore Hydrocarbon Discovery in Lower Congo Basin

Cabinda Gulf Oil Company Limited, a subsidiary of Chevron Corporation, alongside joint venture partners Sonangol E&P, TotalEnergies, and Azule Energy, confirmed an oil and gas condensate discovery at the 105-4X exploration well in Block 0, offshore Angola. The technical operation targeted deep subsurface formations within the Lower Congo Basin to assess hydrocarbon potential for regional energy supply.

Joint Venture Structure and Operational Scope
The exploration project operates under a joint venture consortium where Cabinda Gulf Oil Company Limited serves as the operator with a 39.2 percent working interest. State-owned Sonangol E&P holds a 41 percent interest, TotalEnergies maintains a 10 percent share, and Azule Energy accounts for the remaining 9.8 percent. This consortium model combines operational management, regional regulatory integration, and risk-sharing across complex deepwater offshore environments.

Technical Well Parameters and Subsurface Data
The 105-4X well encountered a continuous oil and gas condensate column exceeding 600 meters in the primary Pinda geological reservoir. Petrophysical evaluation confirmed more than 90 meters of net pay within high-permeability formation rock. The drilling parameters and geological data validate the structural integrity of the reservoir section, providing core subsurface metrics required for reservoir simulation models.

Infrastructure Integration and Development Strategy
The technical assessment focuses on connecting the 105-4X well via subsea flowline infrastructure directly to existing nearby processing platforms. Utilizing an infrastructure-led tie-back strategy avoids the construction of standalone surface production facilities, reducing capital expenditure and shortening engineering lead times between appraisal and commercial extraction. The integrated assets rely on standardized subsea control systems and industrial automation to route raw hydrocarbons into current separation and stabilization trains.

Regional Exploration Context
The Block 0 operation forms part of broader exploration activities across West Africa and Sub-Saharan offshore basins. Operator data indicates the asset integrates into regional operational networks producing approximately 300,000 barrels of oil equivalent per day net. The joint venture partners will conduct further dynamic testing to establish steady-state flow rates and formalize the final field development configuration.
