Following the pad, the ,fracturing fluid, is pumped downhole with a variety of additives. Proppant (sand or ceramics) is viscosified in the ,fluid, and placed into the fractures to prop them open. Before production phase, the ,fluid, needs to break down and be brought back to the surface so it …

Analysis of the ,fluid, returned to the surface (,flowback fluid,) after hydraulic ,fracturing, indicates that as little as 30 to 45% of the guar-based polymer pumped during the treatment returned from the well during the ,flowback, period. 3 Polymer residues that remain in the fracture significantly contribute to lower proppant-pack permeability, leading to a loss in fracture treatment effectiveness. 1

However, field data show that the flowback rate of the fracturing fluid after fracturing is generally no higher than 30% . For conventional reservoir hydraulic fracturing, the flowback rate should be higher to reduce the damage caused by the external fluids to the reservoir [ 2 – 4 ].

Whereas a conventional HF may unload from 200 to 500 bbl of water per well, an unconventional HF may unload from 10,000 to 50,000 bbl of water per well. Conventional HF flowback typically contains emulsified oil, and often contains other stimulation fluids, such as aromatic solvent and/or spent acid.

The primary purpose of hydraulic ,fracturing, is to provide highly conductive paths from the reservoir to the wellbore. This is accomplished by pumping ,fracturing, fluids at extreme pressures to create fractures in the reservoir rock. In addition to creating the fractures, the ,fluid, is used to carry proppant into the fractures to keep them open for flow after the pressure is relieved.

This innovative waterless fracking not only minimizes the environmental risks but also results in increased ultimate recovery compared to conventional water-based fluids – especially in tight and ultra-tight reservoirs – due to its characteristics of ,rapid flowback, and fracture closure, compatibility with the reservoir (no phase trapping) and increased effective fracture lengths.
