Hydraulic fracturing of deep shale formations for hydrocarbon recovery results into the generation of new microbial habitats in the subsurface. Through temporal analyses of produced water samples recovered from multiple, geographically-distinct wells across North America, our research group has revealed conserved patterns of microbial community assembly and carbon cycling in this novel ecosystem. Importantly, insights gained from studies in this environment may be applied to more complex ecosystems such as soils, where physical, chemical, and microbial complexity currently preclude a true mechanistic understanding of ecosystem function.
In his talk “Deep shales as windows into cryptic carbon cycling in the terrestrial subsurface,” Dr. Mike Wilkins will discuss the microbial metabolic networks that develop in the deep subsurface and enable microbial communities to persist in an extreme environment thousands of meters underground for many hundreds of days following hydraulic fracturing. He will also detail the dual role of microbial viruses (‘phage’) in driving strain-level community dynamics and catalyzing carbon cycling in this environment. Finally, he will briefly discuss the applied aspects of the work, and how our investigations into microbial community metabolism may impact oil and gas recovery and infrastructure. Dr. Wilkins is an assistant professor in the Department of Soil and Crop Sciences at Colorado State University.
