Applications
Hydroxypropyl guar gum powder is mainly applied to oil well water-based fracturing as fracturing fluid thickener and features high viscosity, low residue, good water solubility, low water content and water insoluble, less damage to oil reserve of sand rock, easily controlled rheological properties and easy flowback from stratum. It is mainly used as water-based fracturing fluid for hydrofracturing of gas wells and prepad fluid for acidizing operation and is the essential product for high temperature deep well and low permeability oil and gas reservoir fracturing fluid thickening. Meanwhile, it is widely applied to the oilfields all over China and wins unanimous praise from users.
