Hydraulic fracturing (also called as fracking, fracing, hydrofracturing) involves high-pressure injection of ‘fracing fluid’ (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely.

In U.S. Pat. No. 5,330,005, a method of controlling proppant backflow from an underground formation is disclosed wherein the addition of fiber materials to the mixture used for hydraulic fracturing and to the well gravel-packed filter reduces proppant backflow and/or the production of fine grained grit in the packing, thus stabilizing the packing and reducing the consumption of high polymer fluids.

In the fracturing fluid flowback period, proppant particles could be driven away from the pillar by the fluid flow and cause the instability of the proppant pillar. The proppant flowback could occur easily with large proppant pillar height or a large fluid pressure gradient.

Review of the Proppant Selection for Hydraulic Fracturing
Review of the Proppant Selection for Hydraulic Fracturing

The goal of hydraulic fracturing is to create a highly conductive fracture system that will allow flow of fluid and/or gases through the formation to production well. A proppant is a solid material, typically sand, treated sand or man-made ceramic materials, designed to keep an induced hydraulic fracture open.
