Stress Sensitivity of Proppant-Containing Fractures and Its Influence on Gas Well Productivity
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 ...

Method to Predict Proppant flowback in Fractured Gas well [PDF]
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

Feasibility of Proppant Flowback Control by Use of Resin-coated Proppant [PDF]
Proppant flowback is a problem in Xinjiang oilfield. It decreases production rate of a fractured oil well, corrodes surface and downhole facilities and increases production costs. Curable resin-coated sand is a common technique to control proppant flowback.
