The Ukraine crisis caused relations between Russia and the EU to fall to their lowest point since the Cold War. But despite the bickering and outright conflicts, both still need each other: Europe relies on Russian gas to keep warm, and Russia in turn needs revenues. With winter on its way and capital flight from Russia reaching dangerous levels, the outlook should draw the EU and Russia back together.

Oil companies in Russia, the world's biggest producer which has budgeted for $100 crude, played down the oil price drop, saying it would not last and would not damage long term projects.

Schlumberger Ltd, the world's largest oilfield services company, said oil and gas spending would increase in 2015 as global oil demand is poised to rise, downplaying fears of an investment slowdown due to weak crude prices.

As the European calls for diversification away from Russian sources of natural gas continue in the wake of the Ukraine crisis, a just released study from The Brookings Institution shows that the European Union is likely to be using a lot of Russian gas even by the year 2040.

Europe’s natural gas supply mix likely won’t change much without drastic policy interventions despite recent renewed concern over instability in Ukraine, a new Brookings Institution policy brief concluded. This effectively will ensure a continuing significant market share for Russia, it said.

Bulgaria, Finland and Estonia could suffer major gas shortages if Russia cut off all its gas deliveries for six months, according to a report released Thursday by the European Commission.

Bank of America Corp. and BNP Paribas SA predict prices will hold above $80 a barrel. Commerzbank AG also sees that level as a possible low for Brent crude. They’re in part counting on OPEC cutting output -- some say as soon as next month -- to compensate for recent declines in demand.

South African President Jacob Zuma outlined ambitious plans on Wednesday for oil andgas exploration in coastal waters that he said could contain as much as 9 billion barrels of crude and vast quantities of natural gas.

Russian state gas giant OAO Gazprom said second-quarter profit rose 13% on higher sales and prices which offset provisions for non-payment by Ukraine’s Naftogaz.

OPEC is resisting pressure to cut oil production while demand slumps as it tests how low prices must go to make U.S. shale oil unprofitable. As producers become more efficient, that floor is sinking.
