Acid Fracturing Acid fracturing, is a process in which ,acid, is injected at a high enough rate and pressure to fracture the formation which is performed above the fracture pressure of the formation. A viscous pad (a ,fracturing fluid, that does not contain proppant) is pumped into the formation at pressures above the fracture-initiation pressure, which fractures the rock.
