Novak said the cost of shale oil production - between $45 and $60 per barrel - is seen as a benchmark for oil prices. He expects prices to be between $50 and $60 per barrel on average this year - in line with Russia's budget forecasts.

The two PMs were reacting to a preliminary agreement between Russian giant Gazprom and Western energy concerns including BASF, E.ON, ENGIE, OMV and Shell on doubling the transport capacity of Nord Stream in early September.

Top-flight Western firms such as Shell, E.On, BASF, and Engie (formerly GDF Suez) have banded together with Russia’s Gazprom to double the capacity of Nord Stream, with hopes it will be operational by late 2019.

“Russia and OPEC have talked about cooperation in cutting production many times in the past, but the results of that were always dismal and disappointing,” said Nordine Ait-Laoussine, president of Geneva-based consultant Nalcosa and former energy minister of Algeria. “Russia has assumed that when oil prices go down, OPEC countries are in a weaker position and are more likely to be the first to cut its production, and they always did.”

LNG imports by 10 nations in the region that receive the tanker-delivered fuel dropped 3.4% from a year earlier in August, after reaching a two-year high in March, according to data from Genscape. Russian pipeline supplies soared about 20% from a year earlier in August, remaining at the highest level this year, tracking declining crude prices, according to data from Gazprom, the world’s biggest gas producer.

Russia is overhauling its approach to crafting the budget next year to safeguard reserves, highlighting the challenges it faces in steering the recession-hit economy through a downturn in oil prices.

Together, these deals mean that Europe’s big energy companies want to return to business as usual with Russia, despite the continuing conflict in Ukraine and the EU’s continuing sanctions on Russia.

Oil declined for a second day after another Russian official ruled out cooperation on production cuts with OPEC, adding to signs that a global oversupply will persist.

On measures including cash flow, profit margins and share prices, OAO Rosneft, Lukoil PJSC-- Russia’s two largest oil producers -- and OAO Gazprom Neft are performing better than Royal Dutch Shell Plc, BP Plc or Exxon Mobil Corp.

The Turkish Stream project is a Russian proposal which will transport Russian gas to Europe while bypassing Ukraine. The project is planned to carry 63 billion cubic meters of natural gas to Europe via the Turkish-Greek border. Turkey is due to receive 15.75 billion cubic meters out of the total capacity of the pipeline.
