San Mateo Midstream’s planned acquisition of Cardinal Midstream points to a larger Delaware Basin infrastructure story: gas gathering and processing systems are becoming more connected across southeast New Mexico and West Texas.
San Mateo entered into a definitive agreement to acquire Cardinal’s operating subsidiaries for $752 million. The transaction was closed on July 31, 2026.
The acquisition adds Cardinal’s cryogenic natural gas processing plant complex in Loving County, Texas, with approximately 320 MMcf/d of designed inlet capacity, along with about 145 miles of low-pressure and high-pressure natural gas gathering pipelines across West Texas and southern Eddy County, New Mexico.
The map powered by Rextag Energy DataLink shows why the acquisition matters geographically. Cardinal’s plant complex and gas pipeline system are shown alongside San Mateo Midstream pipelines, planned pipeline infrastructure, San Mateo gas processing plants, and Matador acreage across the northern Delaware Basin. The visual pattern highlights how Cardinal’s system extends San Mateo’s existing gas gathering and processing footprint.
The transaction also expands San Mateo’s customer base. Nine of Cardinal’s natural gas gathering and processing customers would be new gas customers for San Mateo. After the acquisition, San Mateo expects its designed natural gas processing capacity to exceed 1 Bcf/d and its gathering systems to exceed 800 miles of pipeline.
Rather than treating the deal only as a purchase-price story, the map frames it as a system-integration story. Cardinal’s assets give San Mateo additional coverage around Loving County, Texas, and create a stronger link between Cardinal’s plant complex and San Mateo’s existing Black River and Marlan processing plants in Eddy County, New Mexico.
The result is a larger and more flexible Delaware Basin gas system. San Mateo expects the combined infrastructure to improve flow assurance and provide more options for moving gas across the northern Delaware Basin.
