Assala Energy has achieved first production at the Grand N’Gongui field in onshore Gabon — an asset first discovered in 2012 but left dormant for over a decade — in a development that illustrates a growing shift toward shorter-cycle, capital-efficient oil projects across Africa.
Located in the Mutamba-Iroru block in Ogooué-Maritime province, the field was originally discovered by VAALCO Energy before being acquired and developed by Assala. Production is expected to reach around 10,000 barrels per day through a phased program of approximately 60 wells. The Gabonese government formally declared the asset commercially viable in February 2026, allowing Assala to proceed with full development.
The project was delivered in approximately 12 months — a compressed timeline compared with multi-year offshore developments. This speed reflects the appeal of phased onshore projects, which allow production to scale progressively while managing subsurface uncertainty and capital exposure, as tighter financing conditions and energy transition pressures prompt operators to favour shorter payback periods.
The project is strategically significant for Gabon, where national production hovers around 200,000 bpd due to declining output from mature offshore fields. Assala produces between 55,000 and 67,000 bpd — a substantial share of total national output — and its development of Grand N’Gongui highlights how independent operators, with lower cost bases and more flexible investment thresholds, are increasingly leading development activity in the country’s maturing upstream sector.
