19/11/2014, · Qianding Li et al studied the reutilization of hydroxypropyl guar fracturing fluid through adding fresh cross linking agent and thickener into flowback fluids to conduct secondary fracturing process. Surfactant-based chemical-flooding process has been widely studied for its advantage on high oil displacement efficiency, and many studies have been conducted [17] – [20] .

26/4/2017, · Biocides are used to kill bacteria in the mix water. Buffers are used to control the pH of the fracture fluid. Surfactants are used to lower the surface tension. Fluid-loss additives are used to minimize fluid leakoff into the formation. Stabilizers are used to keep the fluid viscous at high temperature.
