U. S. Gas

SemGroup provides the infrastructure to gather gas from the wellhead and move it to the marketplace. Located in key areas, our assets offer producers low and high pressure field services, processing and access to competitive markets.


We own and operate approximately 900 miles of gathering pipelines in Oklahoma, including the 50-mile Canton Pipeline that connects our processing facility in Northern Oklahoma to the STACK play in the central part of the state. Our three natural gas processing plants operate with a combined capacity of approximately 525 million cubic feet per day.
