With deeper cuts now not on the agenda, according to OPEC Secretary-General Mohammad Barkindo, the group is exploring other ways the agreement could be adjusted. However, a big part of that effort was undone by the resurgence of Libya and Nigeria, OPEC members exempt from the cuts that together have added 440,000 barrels a day of production in the last two months.
The ministerial talks would be preceded by a meeting of a technical committee involving all OPEC and non-OPEC members now participating in the oil output-cutting deal. Producers have reportedly begun to consider asking the two nations to limit their output.
