Russell CO2 Storage Complex

The Russell CO₂ Storage Complex, developed by PureField Carbon Capture (PCC), is a Class VI carbon storage project targeting the Arbuckle Group in Kansas. The Arbuckle, located about 3,400–3,600 feet below ground, offers favorable storage conditions due to its thick carbonate layers, porosity, and separation from underground sources of drinking water by nearly 2,900 feet of confining strata, including shale, anhydrite, and salt. To meet EPA Class VI requirements, PCC will utilize two primary wells. CSS #1, drilled in 2022 as a stratigraphic test well, was designed and cased to Class VI standards and will be converted into an injection well during operations, later transitioning to a monitoring well in the post-injection phase. MW #1 is a dual-zone monitoring well that enables direct monitoring of the Arbuckle injection zone as well as the overlying confining layers, providing pressure, temperature, and fluid sampling data to ensure containment. This design also allows future re-permitting flexibility if a secondary injection target, such as the Lansing–Kansas City Groups, is pursued.
