Characterization of Proppant Flowback in Hydraulic Fracturing Rough Fractures
Energy Science & 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 ...

Influence of Proppant Size on the Proppant Embedment Depth
ACS Omega, 2022 Hydraulic fracturing is a well stimulation technique involving the fracturing of bedrock formations by a pressurized liquid, in which proppants are added to keep the fracture open after the fracturing operation. The scale discrepancy between the rock specimen and the proppant may bring deviations in the analysis of proppant embedment depth if the fluid-

Experimental Study on Fracturing Fracture Deformation Mechanism of Shale Reservoir
Frontiers in Energy Research, 2022 After large-scale sand fracturing of horizontal wells in shale gas reservoir, fracturing fractures will deform in the production process. However, fracture deformation will lead to the decrease in fracture conductivity and then cause the decrease of gas ...
