The Dark Horse Sour Gas Treating and Carbon Capture Facility
Components of the Piñon assets include:
- A state-of-the-art amine treating facility designed and engineered to treat any concentrations of carbon dioxide (CO2) and hydrogen sulfide (H2S).
- Two-tower sour condensate stabilization system.
- An acid gas injection well (Independence AGI #1) that will sequester H2S and CO2 into Devonian-era rock formations approximately 18,000 feet below the earth’s surface. With respect to permitted single-well injection capacity, the Independence AGI #1 ranks as one of the largest-capacity sequestration wells in the Permian Basin. In fact, the well is the deepest and largest-capacity acid gas injection well in New Mexico.
- 30,000 horsepower of field compression and associated high-pressure gathering pipelines all meeting full NACE specifications to gather any concentrations of H2S/CO2.
- 20-mile, 20-inch sweet gas pipeline that delivers treated sweet/rich gas to multiple third-party processing plants.
The Dark Horse facility has an initial operating capacity of 85 million cubic feet per day. Piñon has purchased a second amine train, which is scheduled to enter service in fall 2021. This will increase the total sour gas treating capacity for the facility to 170 million cubic feet per day. The Dark Horse facility is expandable to accommodate up to four amine trains, representing a capacity of 340 million cubic feet per day.
