Research Abstract

The underground sequestration of Carbon dioxide (CO2) seems to the most prospective and realistic method of reduce the greenhouse gas effect on the earth. To realize the project, it is necessary to understand behavior of injected CO2 in rock. In this research, we made hydraulic fracturing experiments in granite specimens using CO2 as fracturing fluid. The results indicate the tendency that CO2 induces more three dimensionally and widely spreading cracks than water due to its low viscosity. The results suggest that hydraulic fracturing using CO2 can generate efficient cracks for shale gas productionand hot dry rock geothermal extraction, with realizing the underground sequestration ofCO2 at the same time.
