Venezuela's President Hugo Chavez is likely to celebrate the ruling as a vindication of his nationalist confrontation with oil companies, aimed at increasing available funding for state-led anti-poverty programs in the Organization of the Petroleum Exporting Countries member nation.
Closely allied with Cuba's communist government, the socialist leader has cast Exxon Mobil as an icon of the global capitalism that is the pariah of his self-styled revolution. The limited payout in the claim will cut potential liabilities at a time when Chavez is boosting state spending to shore up support in the run-up to his October re-election bid.
An Exxon Mobil representative said via email on Sunday that the decision by the International Chamber of Commerce confirmed that Venezuela's state oil company, PDVSA, does have a contractual liability to Exxon Mobil. The ICC award is for $907,588,000.
Exxon Mobil filed an arbitration claim in 2007 seeking as much as $10 billion in compensation for the Cerro Negro project located in the Orinoco heavy-oil belt that Chavez nationalized along with three other projects in the same area.
Two Venezuelan government sources told Reuters on Saturday that an arbitration panel had reached a decision in the case and that it was favorable to Venezuela. They declined to give the amount Venezuela was ordered to pay.
Venezuela still faces more than a dozen outstanding arbitration claims, including disputes with the U.S. oil firm ConocoPhillips and the Swiss cement maker Holcim, which in some instances could force Venezuela to make payouts in the billions of dollars.
ConocoPhillips was an investor in two of the four Orinoco projects, which turned tarlike oil into valuable light crude. The two companies had in total asked for as much as $40 billion in compensation.
Venezuelan Energy Minister Rafael Ramirez has said the country does not expect to pay more than $2.5 billion for the combined total of the ConocoPhillips and Exxon Mobil arbitration claims.
Exxon Mobil said in 2007 it had invested about $750 million in the Cerro Negro heavy crude project, which was renamed PetroMonagas as part of the state takeover.
In 2008, Exxon Mobil won an injunction against PDVSA to freeze as much as $12 billion in company assets, a ruling that was quickly overturned but sparked furious criticism by the Chavez government and further deteriorated relations between the two.
Oil companies have remained eager to invest in the Orinoco belt, which is considered to hold one of the world's largest reserves of crude, with U.S. oil major Chevron Corp. and Spain's Repsol signing investment deals in 2010 for new multibillion-dollar projects there.
Chavez's steady push to boost control over the country's oil industry starting in 2004 was followed by similar efforts in oil-producing countries ranging from Ecuador to Kazakhstan.
Critics say his efforts have slowed investments that could help lift Venezuela's crude production, which has remained stagnant for years, and left fewer companies interested in its oil fields.
