Angola's Offshore Gas Field Breakthrough: Sonangol Katambi Discovery
A major breakthrough in offshore oil and gas exploration has been achieved off the coast of Angola, where a significant gas discovery has been confirmed at Block 24. The Sonangol Katambi gas field, located about 500 kilometers south of Angola's existing offshore infrastructure network, was initially deemed unviable by BP when it first drilled the site in the mid-2010s. However, with the recent completion of the Katambi-2 appraisal well, operators have confirmed that the reservoir quality is far superior to what was previously thought.
The discovery is significant not only because of its size but also due to the distinct geological signature of non-associated gas accumulations hosted within carbonate and clastic reservoir systems. Unlike the oil-dominated northern blocks, this region offers a unique opportunity for standalone gas development, which has been made possible by recent regulatory reforms in Angola.
The Katambi-2 well intersected two productive intervals with a combined net pay thickness of approximately 331 meters and achieved a stabilised flow rate of 41 million cubic feet of gas per day (MMscf/d) alongside 1,160 barrels of condensate per day. Preliminary modelling suggests output potential exceeding 100 MMscf/d under optimised production conditions.
