Thank you for this really intriguing talk data set! It was very good to see the characterization of the 18O and 2H of the injected fluids as well as the well fluids to provide the geochemical and hydrogeological context. In addition to the microbial characterization of the well fluids, were you able to do the same for the injectved fluids in order to define the “baseline” Thank you – question posed by Barbara Sherwood Lollar (barbara.sherwoodlollar@utoronto.ca)

Hi, I was just wondering if you had any plans to sample any associated gas phases? I see that the proportions of methanogens (and the rest of the microbial) community change over time; it would be interesting to see if any resultant effects are observed in the compositional/isotopic data of any corresponding gas phase too.

Are there any specific set of geochemical parameters that appear to enhance microbial methanogenesis?
