The 2013 World Shale Gas and Shale Oil Resource Assessment, produced by EIA and Advanced Resources International (ARI), noted large shale deposits in China and Argentina. Exploration and drilling is already underway in these countries. For the last two years, China has drilled more than 200 wells, and Argentina has drilled more than 275 wells. Each country has the potential to significantly increase production of shale gas and tight oil.
In Argentina, many international companies hold leases and have drilled wells in shale formations. Much of the initial activity has targeted shale oil and natural gas in the Neuquen Basin's Vaca Muerta shale formation, located in west-central Argentina. National energy company Yacimientos Petroliferos Fiscales (YPF), the largest shale operator in the country, reported production in April 2015 of 22,900 barrels per day (b/d) of oil and 67 million cubic feet per day (MMcf/d) of natural gas from three joint ventures in Vaca Muerta: one with Chevron at the Loma Campana field, a second one with Dow Chemical at the El Orejano field, and a third joint venture with Petronas at La Amarga Chica field. In addition, China's national oil company Sinopec and Russia's national oil company Gazprom have recently signed a memorandum of understanding with YPF to jointly develop shale from the same basin.
