Russia's top ten billionaires have almost doubled their aggregate wealth in 12 months to $139.3 billion, the Finans business magazine reported on Wednesday.

The global economic crisis saw the combined fortunes of the top ten richest Russians fall from 221 billion to 75.9 billion in 2008, the magazine reported.

Since then, however, massive state injections of funds into global financial markets and government support for companies owned by Russian oligarchs has seen the trend bucked.

The 2010 rating of Russian billionaires to be released by Finans next Monday includes 500 people with an estimated fortune of 3.3 billion rubles ($110 million) As many as 77 Russians have a wealth of over $1 billion each.

As before, tycoon and Chelsea football club owner Roman Abramovich is among Russia's three richest people. His fortune will enable him to keep the club afloat for another 100 years, Finans reported.

The identities of the top two richest Russians will be revealed by the magazine on Monday.
