Equatorial Guinea, which is Africa’s third-biggest oil producer, had in January indicated that it wanted to become an OPEC member.
Meanwhile; OPEC has decided to extend cuts in oil output for a further nine months, as part of efforts to raise prices.
But Nigeria and Libya are excluded from cuts as their output remains curbed by unrest.
A similar decision to curb production five months ago failed to increase prices as OPEC members had hoped.
