The deal was strongly appreciated by the investment community for the expansion of the Combined Company to the new crude oil and petroleum product production and supply areas, Rosneft adding 10% of liquid hydrocarbon production and 20% of refining throughput as well as for significant synergies arising from optimization of mutual oil supplies, transport and logistics costs, drilling cost reduction and joint use of production assets’ infrastructure, modern technologies and know-how.

"Why should we do it?" Sechin, known for his anti-OPEC position, told Reuters in Istanbul on Monday evening, when asked if Rosneft, which accounts for 40 percent of Russia's total crude oil output, might cap its own output.

The warming relations between NATO member Turkey and Russia comes as both countries are dealing with troubled economies and strained ties with the West.

Last week, the Organization of the Petroleum Exporting Countries agreed to cut between 200,000 barrels a day and 700,000 barrels a day of their output to reduce a global oil glut. The 14-nation oil-producing group controls over a third of the world’s oil production, but said it also wanted non-OPEC producers to join the effort to curb output.

Total pipeline gas exports through Nord Stream, Yamal, and Brotherhood rose 13% month on month and 7% year on year to 10.108 Bcm in September, the highest monthly flows seen since March and the fifth-highest total recorded for a calendar month.

Russian oil production continuing its slow climb for at least the next five years.

While Tehran wants to set its production target at about 4.2 million barrels per day, Riyadh last week asked its regional rival to freeze its output at 3.6 million barrels per day in return for a production cut.

«Во втором полугодии цены будут колебаться между 40 и 50 долларов за баррель, в среднем по 2017 году мы ожидаем стоимость нефти в диапазоне 50-60 долларов», - сказал глава Минэнерго России.

The deal, worth about $2.02 billion, was approved by the cabinet Wednesday, said an official, who didn’t wish to be named. The cabinet also approved another deal worth $1.24 billion reached by the three companies earlier this year to acquire a 29.9% stake in Russia’s Taas-Yuryakh oil field.

Top Russian producer Rosneft expects the share of hard-to-recover oil production to rise to 11 percent of its total crude output by 2020, from 7 percent this year. Gazprom Neft, the oil arm of state gas producer Gazprom, is raising its share of output of hard-to-recover oil by tapping more reserves at the Messoyakha project and other assets.
