OPEC raised its outlook for oil use in 2018, 2019 and 2020, when it sees demand reaching 98.3 million barrels a day, or 900,000 more than the group projected in its previous annual outlook.

Oil producers would love to see higher prices, but OPEC so far has been unable to cut output. In September, OPEC agreed to have a committee look at potentially cutting production to 32.5 million to 33 million barrels a day, shaving off 700,000 barrels a day — some 2 percent of overall production.

Brent crude futures LCOc1 were trading at $46.29 per barrel at 0705 GMT, up 71 cents, or 1.56 percent, from their previous close. U.S. West Texas Intermediate (WTI) crude futures CLc1 were up 730 cents, or 1.66 percent, at $44.80 a barrel.

OPEC, which pumps about 40 percent of the world’s oil, meets on Nov. 30 in Vienna to try to implement its first cuts in eight years after agreeing to trim output in Algiers at the end of September. Two years ago Saudi Arabia faced an impasse, Al-Naimi said, commenting on OPEC’s decision to pump without limits.

U.S. West Texas Intermediate crude CLc1 fell by 70 cents to $45.97 by 0611 ET and Brent crude LCOc1 was down 69 cents at $47.45. Both contracts were at their lowest since Sept. 28.

The UK-listed oil majors both said they were planning for prices per barrel in the low $50s in 2017 — only a little above current levels — in a sign of the industry adapting to “lower-for-longer” market conditions.

London Brent crude for December delivery LCOc1 was down 29 cents, or 0.6 percent, at $49.42 a barrel by 0750 GMT after settling down 76 cents on Friday. NYMEX crude for December delivery CLc1 was trading down 29 cents, or 0.6 percent, at $48.41 a barrel, after closing down $1.02 on Friday.

Негативное воздействие низких цен, проявившееся в серьезном сокращении инвестиций в нефтедобычу, будет продолжаться третий год подряд, что станет беспрецедентной ситуацией.

Global offshore oil production (including lease condensate and hydrocarbon gas liquids) from deepwater projects reached 9.3 million barrels per day (b/d) in 2015. Deepwater production, or production in water of depths greater than 125 meters, has increased 25% from nearly 7 million b/d a decade ago.

Brent crude LCOc1 was up 22 cents at $50.20 a barrel as of 0845 GMT (4:45 a.m. ET), after falling in the last three days. U.S. crude gained 10 cents to $49.28.

The North American market has continued to "grind slowly upwards" as the rig count, particularly in the US, ticks ahead from troughs seen six months ago, Martin Craighead said during a quarterly conference call with analysts. But "customers need to be more confident of the durability of those prices before making any significant change to their spending patterns," Craighead said.

The worsening OPEC equation presents Saudi Arabia with a difficult choice after its Algiers U-turn: carry a greater burden within the group, ceding market share to other producers, or lose credibility by softening the terms of the deal. In a worst-case scenario, Saudi Arabia will have to cut production by more than 1 million barrels a day, sending the kingdom’s output to a two-year low.

Brent crude futures LCOc1 were down 51 cents, or 1 percent, at $50.28 a barrel as of 0648 GMT. Prices hit $50.13 earlier in the session, the lowest since Oct. 3. U.S. crude CLc1 was at $49.37 per barrel, down 59 cents, or 1.2 percent, from its settlement on Tuesday. It dropped to $49.21 earlier, the lowest since Oct. 10.

Global offshore oil production (including lease condensate and hydrocarbon gas liquids) in 2015 was at the highest level since 2010, and accounted for nearly 30% of total global oil production. Offshore oil production increased in both 2014 and 2015, reversing consecutive annual declines from 2010 to 2013. Production from onshore tight oil plays has increased faster over the past several years and accounts for an increasing amount of total oil production.

"We have built capacity of up to 2.4 million b/d, but [we are] currently producing about 1.9 million b/d," Omar Farouk, the special adviser on international energy relations to Nigeria's oil minister of state, said on the ministry's twitter handle.
