VERONA, Italy, Oct 20 (Reuters) - Russia, already theworld's top oil producer, has the potential to further increaseoil output in the future by up to 200 million tonnes a year, or4 million barrels per day, Rosneft's chief executiveIgor Sechin said on Thursday.
Russia and OPEC are seeking a way to cooperate to prop upoil prices, hit by global oversupply. But consensus must firstbe found inside OPEC for Moscow to join, officials have said.
OPEC agreed in Algiers on Sept. 28 to reduce production to arange of 32.5 million to 33 million barrels per day, which wouldbe its first output cut since 2008. Another meeting on Nov. 30is set to firm up details of the accord.
"In the next year and a half we should see the end ofsurplus (on global oil markets) and the start of the process ofthe situation normalising," Sechin told a forum in Italy, addingthat he saw oil prices rising to above $55 per barrel by then.
Russian oil output jumped by almost 4 percent in Septemberfrom the previous month to 11.11 million barrels per day (bpd),a new post-Soviet record-high, as companies ramped up drillingamid improved oil prices.
Russian officials have said that Moscow would rather freezeoil output than cut, but the level is yet to be agreed. Russia'sbiggest oil companies such as Rosneft, Gazprom Neft and Lukoil are launching new fields in 2016.
"If the market needs it and there are technological andeconomic grounds, Russia may significantly increase oilproduction in the future by up to 200 million tonnes," Sechintold the forum. He did not give a time frame for the increase.
Last year Sechin said Russia could raise oil production toover 14 million bpd in the next two decades.
Russian Energy Minister Alexander Novak plans to meet hisSaudi counterpart Khalid al-Falih this weekend to discusscoordination of possible actions on the global oil market.
Gazprom Neft, the oil arm of Russian state gas firm Gazprom, could slow its oil output growth compared with thecurrent plan if needed, its Chief Executive Alexander Dyukovtold Rossiya 24 TV in an interview broadcast on Tuesday.
