Gupta et. al., 2011 studied Associative polymer systems that extend the temperature range of surfactant gel frac fluids. New thickening system for fracturing was prepared using viscoelastic Surfactant (VES), low molecular weight associative polymer and three or four additives compound. New thickening fracturing fluid showed good clay control, friction reduction, water wetting and post frac fluid recovery characteristics and could be easily converted into high temperature stable foam....[Contd]
===Summary of Slickwater fracturing===
Baker Hughes focused on hydraulic fracturing treatment by using ULW (Ultra lightweight) proppant and low viscosity slick water fracturing fluid. And performing fracturing method in two stages helps in reducing the conductivity damage.
