Cotton Cove

The Cotton Cove CCS 1 carbon storage project is a dedicated CO₂ injection and geologic sequestration project developed by BKV dCarbon Ventures, in Tarrant County, Texas, approximately four miles east-northeast of Azle. The project involves injection of captured carbon dioxide from the nearby Cotton Cove Gas Plant into the deep Ellenburger Group carbonate formations at depths between approximately 8,806 and 11,250 feet. The Texas Railroad Commission has authorized injection of up to 4.0 MMscfd, equivalent to roughly 75,744 tonnes of CO₂ per year, with a planned operational injection period of about 12 years. The project is designed as a non-EOR storage operation under EPA Subpart RR monitoring, reporting, and verification requirements, incorporating continuous measurement of injected volumes, seismic monitoring, groundwater sampling, chemical tracers, and above-zone monitoring wells to verify containment and detect potential leakage pathways. Multiple confining intervals including limestone and shale formations provide geologic seals above the injection reservoir, and monitoring programs are intended to assess pressure behavior, induced seismicity risks, and long-term storage integrity.
