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.
