Characterization of Proppant Flowback in Hydraulic Fracturing Rough Fractures
Energy Science and EngineeringIn the process of fracturing, proppant flowback is unavoidable, and excessive proppant flowback will cause sand plugging in the wellbore, change the morphology of proppant fractures, reduce the effective flow‐conducting capacity of fractures, weaken the ...

Stress Sensitivity of Proppant-Containing Fractures and Its Influence on Gas Well Productivity
Geofluids, 2023 Formation pressure gradually decreases with fracturing fluid flowback and gas production. Due to the stress sensitivity of the fractures, the permeability of the artificial fractures after fracturing becomes lower, which significantly affects gas well ...
