In December, the Mexican government passed an 'energy reform law' that means corporations can now explore and extract the vast oil and gas reserves in Mexico. Bloomberg described this as "the nation’s most significant economic reform since the North American Free Trade Agreement".
The expected inflow of foreign capital means that oil production could increase from 2.5 million barrels a day now to as much as 4 million bpd by 2025. Natural gas production is expected to increase from 5.7 billion cubic feet now to 10.4 billion cubic feet in 2025. Without question this will involve fracking and the use of millions of litres of water.
