Project Description

OXY USA, the operator of the existing Sheep Mountain CO2 production unit, is proposing to drill two new directional CO2 wells (SMU 1-3-M and SMU 6-4-I). The project would take place within the boundaries of their existing operation, on privately owned surface lands, producing BLM and private minerals.

If approved, the operator would use existing roads, powerlines and production facilities. An existing location with current producing wells would be expanded to facilitate the  two proposed wells. Most of the expansion would be reclaimed and re-vegetated soon after the rig leaves the pad. The project is estimated to take two months for each well.

The Sheep Mountain Unit is located approximately 6 miles south of Gardner and has been producing CO2 since the early 1980s. The produced CO2 is piped through an existing pipeline to the Permian Basin in west Texas, where it is injected underground into producing petroleum reservoirs that are in decline to help remove fluid minerals.
