The GPA Midstream Association has been engaged in shaping the midstream sector of the U.S. energy industry since 1921: setting and adopting standards for natural gas liquids; developing simple and reproducible test methods to define the industry’s raw materials and products; managing a cooperative research program that is used worldwide; providing a voice for our industry on Capitol Hill; being the go-to resource for a multitude of technical reports and publications; and so much more. Our annual GPA Midstream Convention has become the meeting place for midstream professionals from around the globe.

Formerly the Gas Processor's Association, GPA serves the midstream energy industry by providing local, regional and global forums for standards development, industry research, education and improvements in operational safety. Publications include standards and methods for analysis, measurement and sampling of natural gas liquids.
