The expansion adds an incremental 200 MMcfd of natural gas to the previously existing 60 MMcfd for a total designed inlet capacity of 260 MMcfd at the Marlan plant.

Matador Resources Co., Dallas, and its midstream affiliate, San Mateo Midstream LLC, have reached startup of San Mateo’s Marlan cryogenic natural gas processing plant expansion in Eddy County, NM.

The expansion adds an incremental 200 MMcfd of natural gas to the previously existing 60 MMcfd for a total designed inlet capacity of 260 MMcfd at the Marlan gas plant.

The expanded plant supports Matador’s development activities in Eddy and northern Lea Counties, NM, and supports existing third-party producer development plans and allows San Mateo to pursue additional third-party volumes.

San Mateo’s midstream system now has a total gas processing capacity of 720 MMcfd across Eddy and Lea Counties (OGJ Online, July 28, 2023).
