The government of Iraq is hoping that a new OPEC deal will help the war-weary country generate enough revenue to help pay for its costly, 2-year-old fight against the Islamic State group. Iraq, whose oil revenues make up nearly 95 percent of its budget, has been reeling under an economic crisis since late 2014, when oil prices began their descent from a high of above $100 a barrel.

Oil prices slipped on Friday as some investors opted to cash out after Brent touched 16-month a high on Thursday, with optimism over this week's OPEC-Russia accord on cutting output giving way to questions on the "sticking point" of implementing the deal.

Russia promised to support a push by the Organization of Petroleum Exporting Countries to reduce a global oil oversupply after the group agreed to cut production by 1.2 million barrels a day on Wednesday. Energy Minister Alexander Novak pledged Russia would cut its own output by as much as 300,000 barrels a day, a stronger move than the previously preferred position of a freeze.

Accordingly, and in line with the ‘Algiers Accord’, the Conference decided to implement a new OPEC-14 production target of 32.5mb/d, in order to accelerate the ongoing drawdown of the stock overhang and bring the oil market rebalancing forward. The Agreement will be effective from January 1, 2017.

OPEC had proposed Indonesia cut oil production by about 37,000 barrels per day (bpd), or about 5 percent of its output, which would dent the already slipping oil rent in Southeast Asia's largest economy. Indonesia's Energy and Mineral Resources Minister Ignasius Jonan, who attended the Vienna meeting, said the only reduction Indonesia could accept was a cut of 5,000 bpd, which had been approved in the country's 2017 budget.

Oil companies around the world have together added $630 billion to their market value this year, the biggest gain in six years following a 30 percent rise in benchmark Brent crude. This follows a $1.2 trillion loss in value last year and $790 billion in 2014 as crude prices plunged.

“We expect demand to recover in 2017, then prices will stabilize, and this will happen without an intervention from OPEC,” Al-Falih said in Dhahran, eastern Saudi Arabia, on Sunday, according to the Saudi newspaper Asharq al-Awsat. “We don’t have a single path which is to cut production at the OPEC meeting, we can also depend on recovery in consumption, especially from the U.S.”

"The general trend and public statements suggest that OPEC can reach a viable agreement for its production and market management." "If we can agree, and I am optimistic, (oil) prices will increase and this is also what the world economy demands."

"Libya is in such a dangerous economic situation, there is no way it can participate in OPEC production cuts for the foreseeable future," NOC Chairman Mustafa Sanalla told delegates at the Arab-Austrian Economic Forum in Vienna on Friday, according to an NOC statement.

“Security and access to funding are the biggest challenges right now to private sector players,” says Kola Karim, managing director of domestic producer Shoreline Energy. “The situation is really tough.”
