After the hydraulic-,fracturing, operation, the ,fracturing fluid, flows back to the wellbore which results in additional drag force to the proppant particles. Consequently, the proppant pillar might lose its stability due to the flow of proppant, resulting in sanding and significant decrease of fracture conductivity.

Abstract Liquid CO 2 ,fracturing, is an outstanding stimulation ,treatment, for unconventional reservoirs, such as coal-bed methane reservoir and shale gas reservoir. However, the viscosity of liquid CO 2 is extremely low, only 0.03 ~ 0.10 cp under reservoir conditions, resulting a very poor proppant-carrying capacity. Meanwhile, liquid CO 2 is a kind of Newtonian ,fluid,, its friction is very large.
