Production from outside the Organization of Petroleum Exporting Countries will grow by 200,000 barrels a day next year, according to the group, which a month ago had projected a drop of 150,000 a day.

Iran has told OPEC it pumped 3.63 million barrels of oil per day (bpd) in August, up 10,000 bpd from July, an OPEC source said, marking a slowdown in the rapid growth that followed the lifting of Western sanctions in January.

Supplies from the Organization of Petroleum Exporting Countries rose by 120,000 barrels a day to average 33.69 million a day in August amid increases by Iran, Iraq and Kuwait, the survey of analysts, oil companies and ship-tracking data showed. The group is due to hold informal talks in three weeks in Algiers, where Russian President Vladimir Putin says an agreement can be reached to limit output.

“We support freezing oil production by OPEC due to the sharp decline of oil prices,” Mr. Abadi said at a news conference, saying it would help government-salaried oil-industry workers.

China Petroleum and Chemical Corporation (Sinopec) has reported a 21.6% drop in net profit for the six months that ended on June 30 as international oil and natural gas prices remained low.

"We have held conversations on strengthening our position in oil markets," Iran's Foreign Minister Mohammad Javad Zarif said through an interpreter after a meeting with Ecuador's President Rafael Correa. Zarif added that the two countries have agreed to continue talks within the framework of OPEC, without providing further details. Ecuador Foreign Minister Guillaume Long said they discussed establishing a common position with regards to strengthening oil prices.

Iran sent a letter to members of the Organization of the Petroleum Exporting Countries saying it would attend the group’s informal talks in Algeria in September, OPEC delegates told The Wall Street Journal. An Iranian oil-ministry press official couldn’t confirm the letter had been sent late Tuesday.

Prices have struggled to go much higher than $50 a barrel. After the longest run of gains since March, Brent crude, the international benchmark, traded 0.9 percent higher at $51.17 at 7:13 a.m. in London on Friday.

OPEC revenue has fallen in step with the steep decline in crude oil prices. The monthly average Brent spot price dropped from $112 per barrel in June 2014 to $38/b in December 2015. OPEC revenue is expected to fall further in 2016 to $341 billion before rising to $427 billion in 2017.

Saudi Arabia, the world’s largest crude exporter, told OPEC that it boosted oil output to a record 10.67 million barrels a day in July, two people with knowledge of the data said. Iran’s output is up to 3.85 million barrels a day, Fars news agency reported, citing Oil Minister Bijan Namdar Zanganeh.
