As the fracturing process proceeds, viscosity-reducing agents such as oxidizers and enzyme breakers are sometimes added to the fracturing ,fluid, to deactivate the gelling agents and encourage ,flowback,. Such oxidizers react with and break down the gel, reducing the ,fluid,'s viscosity and ensuring that no proppant is pulled from the formation.

The purpose of frac ,fluid flowback, is to outflow the fracturing ,fluid, and prevent the proppant backflow, which determines the effect of fracturing ,fluid flowback,. The fracturing treatment in field lacks relevant theoretical models for prediction. Therefore, this work focuses on establishing the ,flowback, model of hydraulic fracturing for multilayer fractured wells.

proved in American research, the amount of the fluid obtained in shale gas fracturing is lower than in the case of a tight oilfield:, 40-60% for a vertical well, and, 10-30% for a horizontal well, [,11, 12,]. The majority of flowback water outflow takes place during the first hours to a dozen or so days. During contact with the deposit, the fracturing fluid

A high salinity fracturing fluid or a surfactant solution can increase the flowback ratio. In addition, the injection pressure is proportional to the flowback ratio, while the matrix permeability and the flowback ratio have an inverse relationship. The adsorption–desorption process of gas has no significant effect on the flowback ratio.
