Testing the frackability of granite using supercritical carbon dioxide: Insights into geothermal energy systems

Supercritical carbon dioxide (ScCO2) fracturing is an attractive method which has favourable physical and chemical characteristics for the enhancement of underground reservoir permeability, and as a replacement for the current water-based fracturing in reservoir stimulation. However, the behaviour of ScCO2 as a fracturing fluid and the reservoir response to the injection of ScCO2 remain unclear in the geothermal environment. Therefore, in this...
