Summary Information
- Operator: Assala Energy
- Country: Gabon
- Location: Two degrees south of the equator in a remote, sparsely inhabited part of the primary rain forest of equatorial Africa, some 140 km south of Port-Gentil, the economic capital of Gabon
- Production start: 1989
- Partners: Assala Energy 100%
- Type: Rabi Light Crude Oil
- Estimated Reserves:
- Production Volume: 23,000 bbl/d in 2010 ( 217,000 bbl/d at its peak in 1997)
Description
- A Giant Oil Field in a Rift Basin, Onshore Gabon
- The oil is pumped to the coast via the Rabi to Gamba Crude Pipeline
Contractors
- **Mott MacDonald:** Installation of a gas injection system to maintain production despite depletion
History
- 1985 - The Rabi-Kounga Field discovered by Shell
- 1989 - The Field came on stream in January
- 2003 - TotalFinaElf announced the signature of an exploration and production sharing contract (ESPC) to replace the concession agreement
- 2009 - Shell increased it share from 44.3% to 94.3% in a Hess asset swap
- 2015 - Wood group awarded engineering, construction, maintenance contract
- 2018 - Assala Energy acquired stakes from both Shell and Total
Geology
- The hydrocarbons are contained within the highly permeable sands of the Gamba and Dentale formations which were deposited in a rift basin of early Cretaceous age, the Dianongo Basin. Trapping is provided by structural closure at the base of the Aptian Ezanga salt.
