Abstract

A process for enhanced oil and gas recovery. An enriched flue gas is synthesized from utility plant flue gas. The enriched flue gas is customizable for specific requirements; however, the gas is formed to have a high concentration of carbon dioxide. This is used as an injectant for enhancing the liberation of gas and/or oil from subterranean formations. The injection elevates recovery while sequestering carbon dioxide from the power plant source.
