Before 2006, almost all of Mexico's natural gas imports came from the United States. More recently, Mexico has diversified its supply sources by importing liquefied natural gas from Nigeria, Qatar, Indonesia, Peru, and Yemen, although the vast majority of their natural gas imports continue to come from the United States.

Pipeline shipments from Texas to Mexico between 2009 and 2012 rose 34% on average per year to 1.3 Bcf/d, which was about 75% of the U.S. natural gas exports to Mexico in 2012. Most of the U.S. exports to Mexico departed the country from Hidalgo County in southwest Texas, where the supplies were likely coming from the Eagle Ford play.
