The key to removal cake during ,flow back, is dependent on the permeability and mechanical properties of the cake itself, irrespective of the initial flow pressure. If the filter cake has low permeability and high yield strength, then the pressure drop on the cake is high, and the cake may be completely stripped and removed from the rock surface.

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.
