PROPPANT-FREE CHANNELS IN A PROPPED FRACTURED USING ULTRA-LOW DENSITY, DEGRADABLE PARTICULATES

摘要

Method comprising introducing a proppant-free fluid into a wellbore penetrating a subterranean formation to create or enhance one or more fractures; providing binding agent-coated proppant comprising proppant coated with a binding agent; and introducing, in alternating order, a proppant-laden fluid and a spacer fluid into one or more of the fractures. The proppant-laden fluid comprises a base fluid and binding agent-coated proppant, and the spacer fluid comprises a base fluid and degradable ultra-low density particulates. And forming a proppant pack in the fracture, wherein the proppant pack comprises binding agent-coated proppant and degradable ultra-low density particulates; producing hydrocarbons through the proppant pack; wherein the hydrocarbons degrade the degradable ultra-low density particulates to leave behind particulate-free channels.
