Southwest Segment

In the Southwest Segment, we gather, process, treat, and transport natural gas and natural gas liquids in East Texas, Southeast Oklahoma, Western Oklahoma, and several smaller systems in the Southwest.

East Texas

Our East Texas operations are located in Panola, Harrison, and Rusk Counties and serve the Carthage Field. The midstream system consists of low and high pressure natural gas gathering pipelines, centralized compressor stations, a natural gas processing facility, and an NGL pipeline.
