Abstract

Approximately 20,000 metric tons of CO2 were injected in the top sequence of the Mississippian age carbonate reservoir to evaluate potential for CO2 Enhanced Oil Recovery (EOR) and to estimate potential of transitioning to geologic CO2 storage through EOR. This paper focuses on tracking of CO2 plume movement in the reservoir using results of reservoir fluid chemical composition monitoring, CO2 plume and injection impact delineation, and studying effects of faults and naturally occurring fractures on fluid movement at the Wellington Field. We found that one of 12 identified and mapped faults worked as a partial barrier to CO2 movement and the associated damage zone and fracture network performed as a flow conduit, determining CO2 flow paths.
