HOUSTON/CARACAS (Reuters) - Malaysian oil company Petronas is exiting one of the biggest petroleum projects in Venezuela's Orinoco belt after tensions with state-run PDVSA over contract terms, three sources close to the venture told Reuters.
The flagship project, called Petrocarabobo, has planned investments of about $20 billion over 25 years and calls for building a 200,000 barrel per day upgrader to convert heavy crude into light crude oil.
State-owned Petroleos de Venezuela (PDVSA) has 60 percent of the project. Petronas belongs to a consortium that holds 40 percent of the project. Its other partners are Spain's Repsol, India's ONGC <ONGC.NS> and two small Indian firms. Petronas holds an 11 percent stake.
"We exited already," said a top executive from Petronas, who was not authorized to speak publicly about the matter. He added that the company will not run any other projects in the OPEC-member country.
