Methods of fracturing using fly ash aggregates

摘要

A method of propping at least one fracture in a subterranean formation is provided, the method comprising: forming a plurality of fly ash aggregates, each fly ash aggregate comprising an aqueous component and fly ash; introducing the plurality of fly ash aggregates into the at least one fracture; and curing at least a portion of the fly ash aggregates into at least one hardened mass. Also provided are methods of fracturing a subterranean formation and methods for the downhole formation of proppant particulates.
