Bravo Dome is a commercial natural CO2 field that supplies the gas to depleted oil fields for enhanced oil recovery. In order to understand the distribution of CO2 across the greater Bravo Dome region, including southeastern Colorado and northwestern New Mexico, and to assess the impacts of high CO2 concentrations on microbes in the subsurface, 7 samples were collected from sites associated with high natural CO2 concentrations. Four water samples were collected, two from wells producing within Bravo Dome, one from an oil and gas field north of Bravo Dome associated with high CO2 concentrations, the Oakdale field, and one sample from a shallow groundwater well on the Rafter K ranch that effervesces CO2. Three samples were collected [...]

The data collected were obtained in order to determine how natural CO2 may impact microbial communities in an attempt to ascertain how sequestered, anthropogenic CO2 may alter the microbial community composition of the target formation. This data could be used to determine how microbial activity may impact the sequestration process in general (e.g., do elevated CO2 concentrations alter the microbial community in a deleterious way), or to predict how microbial communities may shift in response to a CO2 leak into an overlying aquifer.
