New Delhi, April 6: Saudi Aramco, the world's largest oil producer, is keen to pick up a stake in the 60-million-tonne refinery being planned in Maharashtra, while Abu Dhabi National Oil Co (Adnoc) is keen on investing in petrochemical projects.

"Saudi Aramco and Abu Dhabi National Oil Co (Adnoc) are talking to us for investments in the Indian oil sector," oil minister Dharmendra Pradhan said at an event.

"Aramco is talking of stake in the refinery," he said.

He, however, did not say how much stake the Saudi national oil company would pick up. "Let's see," he said.

IOC holds a 50 per cent stake in the project, while BPCL and HPCL have 25 per cent each in the refinery, which will be set up in two phases along with a mega petrochemical complex.

The phase-1 capacity will be 40mt together with an aromatic complex, naphtha cracker unit and a polymer complex. This will cost Rs 1.2-1.5 lakh crore and will come up in 5-6 years from the date of land acquisition.

The mega complex will require 12,000-15,000 acres for which land on the Maharashtra coast has been identified, he said. The second phase, involving a 20mt refinery, will cost Rs 50,000-60,000 crore.

Meanwhile, Pradhan said HPCL's 9mtpa refinery at Barmer in Rajasthan will go on stream soon with the state government agreeing to a revised fiscal package for the project.
