Organization of the Petroleum Exporting Countries (OPEC) said they would cut 800,000 barrels per day for six months from January, causing a sharp spike in oil prices.
Oil prices spiked sharply higher on Friday as major oil producers, including the OPEC cartel, agreed to cut global oil production by 1.2 million barrels a day to reduce oversupply.
Following two days of meetings, the Organization of the Petroleum Exporting Countries that includes the likes of Saudi Arabia and Iraq said they would cut 800,000 barrels per day for six months from January, though some countries such as Iran, which is facing wide-ranging sanctions from the United States, have been given an exemption.
The balance will come from Russia and other non-OPEC countries.
The United States, one of the world's biggest producers, is not part of the deal.
"This is a major step forward," said United Arab Emirates' Energy Minister Suhail Mohamed al-Mazrouei, who chairs the regular meetings in Vienna in his capacity as President of the OPEC Conference.
Oil producers have been under pressure to reduce production following a sharp fall in oil prices over the past couple of months. The price of oil has fallen about 25 percent recently because major producers — including the US — are pumping oil at high rates.
The reduction has certainly met with the response hoped for by ministers as it was at the upper end of most predictions.
Following the announcement, Brent crude, the international standard, was up $2.79 a barrel, or 4.7 percent, at $62.85. Benchmark New York crude was $2.11, or 4.1 percent, higher at $53.60 a barrel.
Ann-Louise Hittle, a vice president at oil industry expert Wood Mackenzie, said the production cut "would tighten" the oil market by the third quarter next year and help lift Brent prices back above $70 per barrel.
"For most nations, self-interest ultimately prevails," she said. "Saudi Arabia has a long-term goal of managing the oil market to avoid the sharp falls and spikes which hurt demand and the ability of the industry to develop supply.
On top of this, Saudi Arabia also needs higher oil revenues to fund domestic Saudi spending."
Russian Energy Minister Alexander Novak called the negotiations with the OPEC nations "fairly challenging" but said the decision "should help the market reach a balanced state."
"I think this is a strong signal to anybody who has doubted it that our cooperation is continuing and we can react to any challenge the market throws at us," he said in Russian through a translator.
OPEC's reliance on non-members like Russia highlights the cartel's waning influence in oil markets, which it had dominated for decades.
The OPEC-Russia alliance was made necessary in 2016 to compete with the United States' vastly increased production of oil in recent years. By some estimates, the US this year became the world's top crude producer.
The cut is unlikely to be greeted warmly by US President Donald Trump, who has been pressuring the cartel publicly to maintain production. On Wednesday, he tweeted: "Hopefully OPEC will be keeping oil flows as is, not restricted.
The World does not want to see, or need, higher oil prices!"
One stumbling block to an agreement had been Iran, Saudi Arabia's regional rival and fellow OPEC member, which had been arguing for an exemption to any cuts because its crude exports are already being pinched already by US sanctions.
Al Mazrouei said that in the end Iran had been given an exemption, as well as Venezuela and Libya.
That "means that the percentage we will contribute among us is going to be a bit higher," he said.
"We within OPEC are committed to distribute the 800 (thousand bpd) among us and deliver on it."
