Reforming Pemex, Mexico's state-run oil and gas company, is a top priority for President Enrique Pena Nieto, and a recent well fire that foreign firms are being brought in to contain is one more reason the 75-year-old monopoly needs to be overhauled. This is great news for big United States oil companies such as ExxonMobil (NYSE:XOM) and service firm Halliburton (NYSE:HAL), as the increased flow of money and technology could triple the amount of proven reserves in Mexico. Investors in offshore drillers will also want to keep their eye on Pemex, as an influx in foreign involvement will directly benefit them.
