The viscosity of fracturing flowback was relatively high due to the guar gum. Therefore, the fracturing flowback was different from conventional oilfield wastewater, which couldn't be treated by flocculation and sedimentation directly. Hence, degrading the molecular chain of guar gum was essential for the subsequent treatment process.

During the process, fracturing fluid leakoff (loss of fracturing fluid from the fracture channel into the surrounding permeable rock) occurs. If not controlled, it can exceed 70% of the injected volume. This may result in formation matrix damage, adverse formation fluid interaction, and altered fracture geometry, thereby decreasing efficiency.
