It is recommended to flow back the well within 6 to 9 hours after the acid fracture treatment to take full advantage of the stored energy and better fluids recovery. Historically, the average acid-flowback period in Saudi Arabia is approximately 5 to 7 days from similar reservoirs. For this particular case, the flowback time was reduced to 3 days.

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.
