Impacts of Proppant Flowback on Fracture Conductivity in Different Fracturing Fluids and Flowback Conditions [PDF]
ACS Omega, 2022 Multistage hydraulic fracturing is used in horizontal wells to increase the production of tight oil. Fracturing fluids are used in hydraulic fracturing to ensure proppants are suspended, but fluid residuals can cause formation damage and reduce rock permeability; meanwhile, fracture conductivity can be further reduced due to the flowback of proppants ...

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 ...

ANALYSIS AND DIAGNOSTIC OF PROPPANT FLOWBACK IN THE ORITO FIELD, COLOMBIA
CT&F Ciencia, Tecnología & Futuro, 2000 Hydraulic fracturing is a conventional practice for production enhancement in low production and damaged wells. Proppant flowback has been a concern in hydraulic fracturing since proppant began to be used as fracture supporting material.

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

Method to Predict Proppant flowback in Fractured Gas well
Procedia Environmental Sciences, 2012 AbstractIt has influences on the production of gas well and the effects of fracture when proppant flowback in the fractured gas well and the loss of the proppant from the fracture will corrupt the equipment above and below ground. For the problem of proppant flowback in fractured gas well, the purpose of this paper is to building a model of predict the
