9/4/2016, · This induces a fracture extending hundreds of feet beyond the wellbore. This allows sand laden water to enter the fracture and prop it open once the pressure is released and maintains an easy path for the ,oil, and gas to ,flow back, to the wellbore. In the early days of fracing ,oil, was the carrying agent and walnut hulls were used as the proppant.
