Supercritical CO2 fracturing is a potential waterless fracturing technique which shows great merits in eliminating reservoir damage, improving shale gas recovery and storing CO2 underground. Deep insight into the proppant-transport behavior of CO2 is required to better apply this technique in the engineering field.
Read More10.5 Fracturing Proppant. Proppants are a key factor of the hydraulic fracturing process. As shown in Fig. 3.20, proppants are small particles suspended within the fracturing fluid base. They are utilized for holding fractures open after the treatment as well as forming conduits for fluid flow into the wellbore [35].
Read More2018.12.15 Proppant crushing, a major proppant failure mechanism, occurs in geothermal energy and oil/gas stimulation production stages when the level of net stress exerted on the proppant exceeds the actual crush resistance of the material. Loss of effective reservoir conductivity due to proppant crushing can result in significant loss in
