Abstract

Summary

The injecting CO2 technique has been successfully applied in conventional and unconventional oil/gas reservoirs for enhancing oil recovery (EOR) and enhancing gas recovery (EGR). That injecting CO2 into a depleted reservoir will not only enhance oil recovery, but will also store the greenhouse gas in the formation. The residual oil or gas saturation are necessary to determine in CO2 injected floods for evaluate EOR or EGR. In this paper, the pulsed neutron gamma logging and resistivity logging technologies were combined to monitor residual oil saturation. The responses of macroscopic capture cross section with formation porosity and oil saturation after injecting CO2 flood were studied by Monte Carlo simulation. Besides, the effects of lithology, water salinity and other factors were also understood. This research provide an effective method to monitor residual oil saturation and CO2 storage in CO2 flooding reservoirs.
