The flowback rate is dictated by the necessity to keep the fractures open. When proppant is used, the fluid flowback rate must be slow enough to prevent viscous fluid forces from pulling proppant out of the fractures. Thus, both conventional and unconventional HF flowback operations occur at similar rates.

Enzyme and chemical hydrolysis are used to degrade the guar at the end of the fracturing treatment. The objective of the hydrolysis is to cleave the b (backbone) linkage, which lowers the molecular weight and reduces the viscosity. However, most hydrolyzing agents indiscriminately cleave both the α (side branch) and the b (backbone) linkage.

A flowback aid may be included in the fracturing fluid to reduce capillary pressure and water blocks, thereby improving the kinetics of the flowback and preventing or minimizing the leaving-behind of any substantial amount of the fracturing fluid. Flowback aids, such as surfactants, have also been shown to aid in the “clean-up” of the proppant pack, thereby accelerating the flow of hydrocarbons through the …

There are major water requirements needed during the entire process of completing each well. For every barrel of crude recovered, up to 7 barrels of water is produced in the form of Flowback Water. This Flowback Water has the potential of becoming the primary source of water needed in both drilling and the completion of the well.
