Xanthan gum (Xanthan gum, XANTHAN GUM) is a high performance biopolymer with excellent rheological properties. Small amounts of xanthan can provide sufficient suspension without adding large amounts of commercial clay solids. XANTHAN GUM Biopolymer is most effective in minimizing potential damage to pay zones and helping optimize drilling practices. At elevated temperatures, xanthan gum provides stable rheological characteristics and gives better results.
Xanthan gum produces drilling fluids with extremely low solids content and excellent bulk and suspension properties. This is due to thixotropy, i.e., with an increase in shear stress, the viscosity decreases, with a decrease in stress, the initial viscosity is instantly restored, which provides:
• minimal settling of drill cuttings in static conditions;
• improved well flushing at lower bentonite concentrations;
• reduction of circulation pressure losses;
• optimal hydraulic mode of the bit, which increases the ROP.
Xanthan gum is a versatile product and can be used in most types of water-based solutions. It is also compatible with most of the other drilling fluid additives most commonly used in these fluids, although it is always recommended that prior testing be performed before using any questionable product combination.
Xanthan is effective in freshwater and brine-based drilling fluids, as well as a variety of workover and brine-based injection fluids over a wide pH range.
