oa Thin Under Gas Oil Rims - New Technology for Efficient Oil Production Using Foam Generating Oil/Water Polymers

Worldwide experience shows that oil production from thin onder gas cup zones with active aquifer is not efficient doe to quick gas/water breakthrough and depends on oil column thickness and the ratio between gas cap and oil part thickness. New WAG Technology based on injection of water solution of oil/water soluble polymers for efficient oil production from thin (5-15m) oil rims have been developed. Results of lab studies and simulation are discuseed. New WAG technology can be used for production of both, light and heavy oils. For heavy oils this technology can be considered to be as altemative to thermal EOR.
