BUENOS AIRES—Argentina's YPF SA YPFD.BA -0.35% and Malaysia's Petroliam Nasional Bhd. will sign an agreement on Thursday to develop shale oil in Argentina's massive Vaca Muerta formation, people familiar with the matter said.
The deal will entail an initial investment of more than $500 million. If it is structured similarly to a joint venture the Argentine company signed last year with Chevron Corp.CVX +0.09% , state-run YPF and Petronas could invest up to $9 billion over the next decade to develop the full potential of La Amarga Chica, an oil field within Vaca Muerta. The 72-square-mile field is in remote, windswept Patagonia.
YPF's deal with Chevron to develop a bigger nearby field has already turned that area, Loma Campana, into the second-biggest producer of unconventional oil outside North America, YPF has said. YPF and Chevron have invested more than $2 billion and are producing more than 25,000 barrels of shale oil a day at about 245 wells.
The Petronas agreement is expected to be similar to the Chevron deal. Chevron invested an initial $1.2 billion, and the total investment by the U.S. and Argentine companies could reach $16 billion in the next 15 years.
YPF and Petronas plan to use hydraulic fracturing to drill several dozen wells in a pilot phase and as many as 1,000 wells over the coming decade. YPF's deal with Chevron could lead to about 1,500 wells drilled.
If fully developed, Vaca Muerta could do for Argentina what fracking did for production of oil and gas in the U.S. That, however, could require an investment of up to $200 billion across the industry, said Bernard Weinstein, associate director of the Maguire Energy Institute at Southern Methodist University.
In addition to cash, Petronas will provide YPF with technical know-how in developing unconventional energy through Progress Energy Resources Corp., a Canadian company that Petronas bought for $5.2 billion in 2012.
The agreement is a win for YPF Chief Executive Miguel Galuccio, who has lived in Southeast Asia, speaks basic Malaysian and has worked with Petronas in the past. Since becoming CEO in 2012, Mr. Galuccio has moved hard to develop Vaca Muerta. Analysts have said that Vaca Muerta, which means dead cow, is one of the world's most promising unconventional energy formations.
Argentina ranks second in the world, behind China, in potentially recoverable shale-gas resources, with 802 trillion cubic feet, according to the U.S. Energy Information Administration. Argentina ranks fourth world-wide in shale-oil resources, with an estimated 27 billion barrels.
