  • Publication number: 20150369027
    Abstract: An in situ channelization method, treatment fluid and system for stagewise reduction of the treatment fluid viscosity. A method involves injecting a treatment fluid into a fracture, decrosslinking a polymer in a first viscosity reduction stage to trigger channelization of a first solid particulate in the fracture prior to closure, and completing a break of the polymer following fracture closure. A treatment fluid may include a carrier fluid, a first solid particulate, anchorants, a delayed decrosslinker, and a further delayed breaker. A system may include a pump system to fracture a formation with a treatment fluid, a carrier fluid which is a continuous aqueous gel phase comprising a polysaccharide crosslinked with a polyvalent cation or a borate anion, a first solid particulate, a hydrolyzable acid-forming precursor, an anchoring system and a shut-in system.
