Operating electric submersible pumps in a CO2 flood is challenging and requires applying new engineering and operational resources to be successful. Extremely high GLR"s, radically changing bottom hole pressures and changing fluid densities require more than just conventional methods for operating and troubleshooting ESP"s. An integrated control system was used to troubleshoot well conditions that consist of high concentrations of CO2. Accurate bottom hole pressure, temperature and vibration information was collected and used to determine actual well conditions and make decisions based on real data.This application decreases the "guess work" previously used in determining bottom hole conditions and increases the effectiveness of decision making to correct problems. This paper is a continuation of work efforts that were started and discussed in last year's SWPSC.
