This document discusses the potential of Argentina's Vaca Muerta shale formation to become a major producer of oil and natural gas. It presents three scenarios for production growth from Vaca Muerta between now and 2040 based on different assumptions about investment levels and economic conditions. Under the base case scenario, Vaca Muerta could add 560 thousand barrels per day of oil and 6 billion cubic feet per day of natural gas by 2040, recovering over 2800 million barrels of oil and 33 trillion cubic feet of gas. For this level of production to be achieved would require annual investments of around $8 billion and sustained foreign investment. Production growth from Vaca Muerta would not be immediate and would depend on maintaining stable economic policies to encourage investment
