Many of Opec’s smaller members pushed for the cut after seeing oil prices plunge from $110 a barrel over the past two years due to oversupply and slowing demand.
Nigerian Oil Minister Emmanuel Ibe Kachikwu said it was a“very positive deal” while Algerian Energy Minister Noureddine Bouarfaa said: “The decision was unanimous and without reservations.”
“The outline deal will limit output from Opec countries to between 32.5 million and 33 million barrels a day,’’ Qatar’s energy minister and current president of Opec, Mohammed Bin Saleh Al-Sada said.
Current output is estimated at 33.2 million barrels per day, although Iraq questioned on Wednesday how Opec measures the oil production of its members.
‘Sceptical on the deal’
Some oil traders remain sceptical about the deal, saying “they want to see the full terms, including the cuts agreed by individual members states, before passing judgement.”
Director of energy markets at Stratas Advisors, Jeff Quigley stated that it was ‘too preliminary’ to get excited.
“The devil’s in the details here,” Mr Quigley said.
“And for them to say it’s going to start in November is very suspect to me. We don’t know yet who’s going to produce what,’’ he added.
The oil producers’ cartel Opec has agreed a preliminary deal to cut production for the first time in eight years, sending crude prices surging.
The major oil exporting nations struck the deal at talks in Algeria on Wednesday to ease fears of oversupply.
“Opec made an exceptional decision today,” Iran’s Oil Minister Bijan Zanganeh said.
Brent crude, the international benchmark for oil, rose almost 6% to nearly $49 a barrel on the news.
Oil ministers said full details of the agreement would be finalised at a formal Opec meeting in November.
Output will fall by about 700,000 barrels a day, although the cuts will not be distributed evenly across the cartel, with Iran being allowed to increase production.
Disagreements between Iran and its regional rival Saudi Arabia had thwarted earlier attempts to reach a deal.
