Best Answer: To fracture. Fracturing (fracing, pronounced fracking) is used to stimulate production in oil and gas wells. Fluid is pumped into the well at pressures high enough to fracture the oil/gas bearing formation. The fracture provides an easier path for fluids in the formation to flow back to the wellbore.
