Extract from the EIA country analysis brief:
“Historically, Gabon’s oil production has been concentrated in one large oil field and supported by several smaller fields. As the largest field matured and production declined, a larger field would emerge and replace dwindling production. Dominant fields have included Gamba/Ivinga/Totou (1967-1973), Grondin Mandaros Area (1974-1988), and Rabi (1989-2010). Gabon’s greatest success, the Rabi oil field, significantly boosted the country’s total output in the 1990s and reached 217,000 bbl/d at its peak in 1997. Although Rabi is still one of Gabon’s largest producing fields, it has matured and production has gradually declined to about 23,000 bbl/d in 2010. Since Rabi’s descent, a new large field has not yet emerged, since recent exploration has yielded only modest finds.”
