PETROALLIANCE, the only Russian oil service company competing locally with Western giants like Halliburton and Schlumberger, is braced for a mighty expansion as a sea change takes place in the way Russian oil companies operate, says company president Aleksandr Dzhaparidze. PetroAlliance reckons its turnover this year will tally between $80 million and $90 million, doubling 1999's effort, on the basis that it has more services to offer Russian oil companies.
