The Impact of Stress on Propped Fracture Conductivity and Gas Recovery in Marcellus Shale
, 2018 It is commonly observed that the production rates from unconventional reservoirs decline rapidly as compared to conventional reservoirs. The net stress increases with the production because the pore (fluid) pressure decreases while the overburden ...

Study on proppant flowback mechanism during post-fracturing stage based on CFD-DEM
Earth Energy ScienceProppant flowback in the post-fracturing flowback period not only reduces the fracture conductivity but also damages equipment. Due to the current lack of experimental or numerical simulation methods for proppant flowback in partial closure fracture, the
