Equatorial Guinea Oil: Production, Reserves & Role in the Market
Equatorial Guinea produces about 0.08 million barrels of crude per day (2025). A small Central African nation that became, briefly, one of the highest-output-per-capita oil producers in the world after the offshore Zafiro field came online in the 1990s — output has since fallen by roughly two-thirds from its mid-2000s peak, and it is now OPEC's smallest member by production.

From Boom to Steep Decline
The 1990s–2000s boom
- The 1996 discovery of the Zafiro field triggered a rapid production ramp-up that, for a time, gave Equatorial Guinea one of the highest oil revenues per capita of any country in the world despite its small population.
- Output peaked in the mid-2000s as Zafiro and other offshore fields reached full production.
Why it joined OPEC in decline, not growth
- Equatorial Guinea joined OPEC in 2017, by which point production was already down to roughly half its peak — the government hoped membership would help attract renewed investment and technology transfer from other members.
- Decline has continued since: by 2022 output had fallen to levels last seen around 2000, roughly a third of the mid-2000s peak, reflecting the natural depletion of aging offshore fields with limited new exploration success.
