1/9/2015, · Similarly, back-producing proppant into a wellbore can happen as a consequence of any intentional or unintentional flowback, which may occur after hydraulic fracturing, during pressure redistribution when wells are shut in [e.g., a water hammer during a hard shutdown can send a pressure pulse into and subsequently out of a fracture (Santarelli et al., 2011)], and during production).

Proppant flowback mainly occurs in the early stage of fracturing fluid flowback; more than 75% of the flowback volume of the proppant was carried by 33.33% of the fracturing fluid flowback volume. The weight of the flowback proppant decreases as the flowback fracturing fluid viscosity decreases. Using a larger particle size proppant or upon increasing effective closure pressure also can decrease the …

was fluid inflow at zones 1 and 2, but not at zone 3. Proppant backflow was identified exactly where the operator had conducted hydraulic fracturing, which is a clear indication that the fracture was not working as per the design intent. Hence the hydraulic fracturing needed complete reassessment and re-design.

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.

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.

Abstract One of the concerns of using ,proppant, in geothermal wells, and particularly in enhanced geothermal systems, is ,proppant, flowback. Particulate ,proppant, maintain post-closure conductivity in hydraulically opened fractures. If that ,proppant, is displaced from the near-wellbore region, either due to overflushing during stimulation or flowback to the wellbore at any time, the reduced ...

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.

However, if the fracturing fluid flowback velocity is too high, it will result in proppant backflow. Therefore, a reasonable flowback velocity and optimized choke will benefit the design of the fracturing fluid flowback system. Proppant backflow directly affects the results of hydraulic fracturing construction.
