Abstract:
Compositions for suspending proppants in a hydraulic fracture of a subterranean formation involve a carrier fluid, a plurality of proppants, and a plurality of filaments, which optionally are comprised into a fabric that includes a plurality of connected filaments. The filaments contain crosslinkable sites, e.g. organo-borate, organo-zirconate, organo-titanate, and/or hydroxyl groups. A method of using the compositions includes hydraulically fracturing the subterranean formation to form fractures in the formation, during and/or after hydraulically fracturing the subterranean formation introducing proppants into the fractures, during and/or after hydraulically fracturing the subterranean formation introducing a plurality of filaments into the fractures, where the filaments contact and inhibit or prevent the proppant from settling by gravity within the fractures; and closing the fractures against the proppants. Inhibiting and/or preventing the proppants from settling is improved by the crosslinkable sites crosslinking a polymer present in a fluid contacting the filaments; e.g. a polysaccharide.
