Over the past several years MDN has highlighted important research performed by Ohio State University with respect microbes (bacteria) living in shale wells. In a 2016 study, researchers dubbed a never-before-seen bacterial “lifeform” found in a Utica Shale well, Frackibacter. Having some fun, we labeled it a different name: Frackenstein (see Frackenstein! Researchers Find New Life Form in Fracked Utica Wells). The researchers kept at it and published another study along the same lines in 2017 (see Ohio State Research Finds Microbes in Utica Well May be Corrosive). Researchers said a different bacteria studied that appeared in multiple Utica wells (called Halanaerobium) may be a cause for concern, possibly corrosive to pipes and cement and toxic for workers. OSU researchers have kept at it and we now have a brand new study, titled “Members of Marinobacter and Arcobacter Influence System Biogeochemistry During Early Production of Hydraulically Fractured Natural Gas Wells in the Appalachian Basin” (full copy below). This time, several Utica and Marcellus wells were studied. What’s the upshot of this latest study?
