The pressure of the frack ,fluid, on the target formation causes the target formation to fracture, whilst the proppants in the frack ,fluid, hold open the fractures. This ,fracturing, of the target formation causes the permeability of the formation to be artificially increased and allows the oil and gas to flow more freely back into the wellbore.
