Large volumes of water containing chemical additives and microbial biomass are injected into the subsurface during hydraulic fracturing of black shale. Biotransformation of chemical additives occurs when microorganisms degrade organic additives in fracture fluids stored on site, and brines produced from the well. Biodegradation of organic compounds has important ramifications on gas productivity through poor proppant placement, fracture clogging, gas souring, and corrosion of well infrastructure. It also has serious implications on human health when unintended toxic metabolites are generated in production brines and require management at the surface. This talk presents genomic and mass spectrometry information supporting the presence and role of microbial communities in degrading organic contaminants, with examples from Marcellus and Utica shale wells.
