A deal between French energy group Total and Russian gas firm Novatek shows that oil majors have an appetite for Russia's energy riches despite the Yukos affair, but also the limited role now possible for foreigners in this strategic sector, analysts say.
Total said last week that it had signed an agreement to acquire a quarter share of the small but fast-growing gas producer Novatek for a undisclosed price tag estimated at a billion dollars.
US oil major ConocoPhillips is expected on Wednesday to pick up a 7.6-percent stake in Russia's number two oil producer LUKoil at auction for 2.0 billion dollars or more (about 2.0 billion euros) - the biggest deal since BP of Britain bought 50 percent of Russian oil group TNK last year.
"Totals acquisition marks a pickup in foreign investment in the Russian oil and gas sector which has seen something of a hiatus since the TNK-BP deal last year," Stephen O'Sullivan at the United Financial Group brokerage in Moscow commented.
"Overall this is a positive development for Russias investment climate," he said.
Total had eyed a stake in Sibneft, the fifth-largest Russian oil producer which last year broke off a merger with the number one Yukos after it became locked in a battle with the Kremlin that threatens to drive it into state control.
But Sibneft's continued entanglement with Yukos forced Total to look for another target, and it went for Novatek, a firm created in 1994 and which accounts for 3.3 percent of Russia's gas output, dwarfed by the state-owned monopoly Gazprom.
ConocoPhillips, keen to acquire at least 20 percent in LUKoil, which has proven reserves of almost 16 billion barrels of crude, may have to settle for the 7.6-percent state shareholding on offer.
An analyst from Renaissance Capital finance house in Moscow, Adam Landes, says Western oil giants with their dwindling reserves are knocking at the door in Russia, the world's second-largest oil exporter after Saudi Arabia which has vast untapped crude resources.
"There are compelling resource and economic reasons why international oil companies are attracted to Russia," he said.
But under President Vladimir Putin, the rules of the game have gradually changed in a more state-dominated environment which no longer welcomes major foreign equity involvement in the oil and gas sector.
"There doesn't appear to be a big interest on the part of Russia to have foreign owners controlling strategic parts of the industry," Landes said.
Last October, US oil major ExxonMobil was reported to be negotiating to purchase up to 40 or 50 percent or more of shares in the merged company being created by Yukos and Sibneft.
That potential deal, which would have handed control of the largest Russian oil producer to a US rival, may have been a factor in the state's campaign to rein in Yukos' main owner, politically ambitious tycoon Mikhail Khodorkovsky, analysts say.
"It was one of the reasons Yukos has ended up where it is today, the government did not want to see Yukos get into the hands of foreigners," Valery Nesterov of Moscow investment firm Troika Dialog said.
A western oil executive in Moscow recognizes that BP's half-ownership of the number four oil group in Russia, which was personally blessed by Putin, is not an option open to other foreign firms.
"It is difficult for us to move into big Russian companies, we are left with the medium-sized ones. There was one big deal on the table, it was TNK which BP snapped up in 2003," he said.
