Field trials were carried to evaluate the highly-conductive, proppant-free channel (PFC) fracturing method. Pulsing or intermittently injection of proppant-free and proppant-aggregate-laden fluid stages can be done with existing equipment with some modifications. Proppant aggregates were formed with a coating of an agglomerating agent. Proppant-free spacer fluid should remain stable to hold proppant beds in place until after closure of the fracture to ensure channel formation between proppant beds. The PFC fracturing method allowed treating pressure to remain steady or decrease during placement of proppant beds into the fracture. Hydrocarbon production of PFC-treated wells was equal or greatly better than those completed using conventional hydraulic fracturing treatments.
