Hydroxypropyl guar gum is a new type of low-damage fracturing fluid thickener produced through chemical modification of guar gum
Hydroxypropyl guar gum is a new type of low-damage fracturing fluid thickener produced through chemical modification of guar gum. It boasts high viscosity, low residue, good water solubility, low moisture and water insolubles. Thanks to little damage to sandstone reservoir, easily controlled rheological behavior and easily flowback from stratum, it is mainly used as water-based fracturing fluid in fracturing of oil and gas well and prepad fluid in acidizing treatment. It is a must for thickening in fracturing of deep wells with high temperature and low permeability.
Hydroxypropyl guar gum powder fracturing fluid is a low damage fracturing fluid, suitable for fracturing of low permeability reservoir at 30°C-150°C. It is widely applied in oilfield fracturing, sand control, water control operations.
