Delaware Basin
With 36 processing and treating facilities and more than 3,400 miles of pipeline, our assets are located in the heart of the Delaware Basin, one of the most active basins in the U.S.
Oil
Our DBM oil system features four central production facilities and two Regional Oil Treating Facilities (ROTFs), which centralizes stabilization activities and reduces our environmental footprint. Read more about our ROTFs on our COSF/ROTF page.
Natural Gas
WES provides gas gathering, treating, and processing services throughout the Delaware Basin in Culberson, Loving, Reeves, and Ward counties in Texas, and Eddy and Lea counties in New Mexico.
Western Midstream operates three gas processing facilities and has over 2.190 Bcf/d of processing capacity.
Water
In October 2025, WES acquired Aris Water Solutions, solidifying WES’s position as one of the largest three-stream midstream, flow-assurance providers in the Delaware Basin, and adding approximately 790 miles of produced-water pipeline, 1,800 MBbls/d of produced-water handling capacity, 1,400 MBbls/d of water recycling capacity, and 625,000 dedicated acres to WES’s existing produced-water infrastructure. WES’s assets now extend into Lea and Eddy Counties, New Mexico, and include the McNeill Ranch that spans Texas and New Mexico.
WES operates more than 130 saltwater disposal wells with more than 3.8 MMBbls/d of disposal capacity, as well as 1,400 MBbls/d of recycling capacity.
