POLYMERIC AND ELASTOMERIC PROPPANT PLACEMENT IN HYDRAULIC FRACTURE NETWORK

摘要

Methods may include treating a subterranean formation penetrated by a wellbore, including: pumping a treatment fluid containing one or more polymeric proppants into the formation at a pressure sufficient to initiate a fracture, wherein the one or more polymeric proppants are composed of one or more polymers selected from a group of polyethylene, polypropylene, butylene, polystyrenes (PS) and copolymers thereof, high-impact grafted polystyrene (HIPS), acrylic polymers, methacrylic polymers, polyvinyl chloride (PVC), polyvinyl acetate (PVA), polycarbonate (PC), hydrogenated nitrile butadiene rubber (HNBR), ethyelene propylene diene monomer (EPDM), polydimethylsiloxane (PDMS), natural rubber, polystyrene-polybutadiene (PS-PB) copolymers, polymethylmethacrylate (PMMA), polystyrene-block-polymethylmethacrylate (PS-b-PMMA), acrylonitrile butadiene styrene (ABS), and epoxy resins. Methods may also include introducing a multistage treatment fluid comprising one or more stages of a polymeric proppant-containing fluid and one or more stages of a spacer fluid into one or more intervals of a wellbore.
