DESCRIPTION:
XC-Polymer (Xanthan gum
biopolymer) is a premium grade viscosifier for oilfield drilling, work-over
and completion fluids. It is a high molecular weight polysaccharide produced
by fermentation of carbohydrate with Xanthomonas Campestris and shows shear thinning
properties.
APPLICATION:
XC-Polymer solutions display
exceptional shear thinning properties and good suspension characteristics
even in the absence of inorganic colloids. This allows for high penetration
rates, hole cleaning and pay zone protection. The product is particularly
suggested for the preparation of polymers mud system. XC-polymer shows good
temperature stability up to 300oF.
