The EIA is reporting that oil swaps with Mexico will bring economic and environmental benefits to both countries.

Last month, the U.S. Department of Commerce opened the door for a limited amount of oil to be exported to Mexico through an exchange program that will allow the U.S. to 'swap' its light sweet crude for Mexican heavy sour crude.

Light sweet refers to crude with a sulpher content of less than 0.42%. Currently, U.S. Gulf Coast refineries are better suited to process heavy sour crude and Mexican refineries are more equipped to process lighter crude. The swap will allow the two countries to optimize their existing refining processes and increase the supply of lower-sulfur gasoline from Mexican refineries.

The Energy Information Administration (EIA) released a report last week saying that there may be significant environmental benefits from such oil exchanges.

Currently, U.S. Gulf Coast refineries are better suited to process heavy sour crude and Mexican refineries are more equipped to process heavier crude.

Many are hoping this new policy signifies a shift in opinion about the oil export ban that has been in effect since the 1970’s, but some analysts believe the effort may be mostly symbolic.
