Several OPEC members want to revive the idea of setting new limits on oil production this fall as Iran regains much of the energy-industry might it lost during the years of Western sanctions, according to people familiar with the matter.

The nations—which include Venezuela, Ecuador and Kuwait—want to take another stab at cooperation between the 14-nation oil cartel, the Organization of the Petroleum Exporting Countries, and nonmembers like Russia.

A similar initiative died back in April during talks in Doha, Qatar, when Saudi Arabia backed out over Iran’s refusal to join in a so-called production freeze until it had reached pre-sanctions levels of oil production. Under the freeze, countries would have agreed to limit their production to certain levels in a bid to raise oil prices by constricting the amount of crude on the market.

Now, Iran’s production has crept back up to 3.6 million barrels a day, about 180,000 barrels a day above its levels in April and almost 600,000 barrels a day higher since world powers lifted economic restrictions on the country over its nuclear program in January. That brings it within reach of the 4 million to 4.2 million barrels a day that Iranian officials said they would require before agreeing to a freeze.

A spokeswoman for Iran’s oil ministry declined to comment on whether Iran could now consider joining an output freeze.
