Innovative High-Salinity Water Based Fracturing Fluid for High-Temperature Applications: Reducing Freshwater Demand at Lower Cost
Guar-based gel fluids are widely used in hydraulic-fracturing, because of salt resistance and high viscosity performance. To save freshwater usage, high salinity water was used as base brine for guar gel formulation. Different guar gum and guar derivatives including HPG and CMHPG were evaluated, in terms of molecular...
