Piñon building Delaware basin sour gas treatment, carbon capture

Piñon Midstream LLC is building the greenfield Dark Horse sour gas treating and carbon capture site and associated pipeline infrastructure in northeastern Delaware basin, Lea County, NM. The project includes a centralized amine treating plant, an 18,000-ft deep acid-gas sequestration well (Independence AGI #1), and 30,000 hp of field compression.

Piñon expects Dark Horse to begin operations in July 2021, treating 85 MMcfd of sour gas. The company purchased a second amine treating plant that is scheduled to be installed and operational in fourth-quarter 2021, increasing capacity to 170 MMcfd.

The site is expandable up to 400 MMcfd.

Treated gas will be delivered to multiple third-party gas processing plants.
