Hydroxypropyl Guar Gum is an Non-Ionic guar derivative used as low damage fracturing fluid thickener produced through chemical modification of guar gum powder. It boasts high viscosity, low residue, good water solubility, low moisture and water insoluble.
It causes minimum damage to sandstone reservoir, easily controlled rheological behavior and causes easy flow-back from formation. It is mainly used as water-based fracturing fluid in fracturing of oil and gas well as well as prepared fluid in acidizing treatment. Once cross-linked, it exhibits excellent carrying capacity to support sand or other proppants to be placed in the created fracture. The viscosity can be reduced or broken with the use of enzymes, oxidizers or acids such as HCl.
