“…27 Genomic analysis identified putative CO 2 -utilizing pathways among the bacterial groups, and no archaeal phyla were found. 27,28 Metagenomes recovered from Crystal Geyser, a subsurface CO 2 -saturated aquifer in Utah, revealed a phylogenetically diverse microbiome consisting of largely unclassified chemolithoautotrophs. The authors postulated that carbon fixation via CO 2 assimilation is utilized by the microorganisms thriving in the CO 2 -saturated environment.…”

The injection of supercritical CO2 into depleted oil reservoirs for long-term storage will influence the subsurface biogeochemistry with important implications for future carbon storage sites. In this study, we characterized produced water collected from CO2 enhanced oil recovery (CO2 EOR) well separators in the Niagaran Pinnacle Reef, an oil-producing region in the Michigan Basin that is a proposed target for future geological carbon storage. Our analysis investigated the geochemical and microbial community composition of produced water to understand the overall biogeochemistry in subsurface environments exposed to conditions expected during carbon storage in a depleted oil reservoir. The majority of sampled wells were characterized by high salinity and high total dissolved solids ranging from 122,000 to 416,000 mg/L. In addition, the sample wells contained supercritical concentrations of CO2 (scCO2) that appeared to drive low microbial community abundance among the sampled wells. We also observed minimal well-to-well communication, suggesting low permeability and reduced fluid migration within the reservoir system, which likely fostered isolated evolution of the reservoir microbiomes. The predominant microorganisms observed have been described in previous carbon storage systems, including Desulfotomaculum, Sulfurospirillum, Halanaerobium, Acetobacterium, and Pseudomonas. These taxa may participate in microbial processes such as sulfide and acid production, biofilm formation, and biomineralization. These metabolic processes can impact reservoir quality and stability and long-term carbon storage. Overall, these results suggest that these subsurface reservoirs select for stress-tolerant microbial communities that are adapted to high salinity and scCO2 exposure. This work contributes to a greater understanding of the site-specific microbiology in a reservoir targeted for long-term CO2 sequestration.
