OREANDA-NEWS. Indonesia's state oil firm Pertamina is set to buy a stake in Iraq's giant West Qurna oilfield from Exxon Mobil, joining PetroChina in the USD 50 billion project, industry and Iraqi oil sources said.

 The deal could be Pertamina's largest foreign acquisition and mark its first move into Iraqi oil and gas production since U.S.-led forces toppled leader Saddam Hussein in 2003.

 As things now stand, Pertamina is likely to take a 10 percent stake in the project at the southern oilfield, now pumping nearly 500,000 barrels per day, the sources said.
