Borate Crosslinker for Fracturing Fluids
Borate crosslinker is an aqueous alkaline solution of sodium or potassium tetraborate used to crosslink guar gum and hydroxypropyl guar (HPG) base fluids into high-viscosity elastic gels for hydraulic fracturing. Crosslinked gels achieve viscosities of 1000–5000 cP, providing superior proppant transport and fracture width support compared to uncrosslinked fluids. Borate crosslinks are thermally reversible, allowing effective gel breaking and cleanup after fracturing.
