Qualitative and quantitative evaluation of the alteration of micro-fracture characteristics of supercritical CO2-interacted coal
CO 2 geo-sequestration necessitates injection of CO 2 into coal reservoirs, in which CO 2
becomes supercritical due to high pressure/temperature conditions. Consequently, the coal …
