Hydraulic ,fracturing, is a controlled, high-pressure injection of ,fluid, and proppant into a well to generate fractures in the rock formation containing the oil or gas. After the hydraulic fracture procedure is completed, the injected ,fluid, is allowed to ,flow back, into the well, leaving the proppant in the newly created fractures.
