VerXan™ gum, Cargill’s high-molecular weight biopolymer, provides versatile rheology control in a wide range of brines, drilling and fracturing fluids. Xanthan gum is considered non-hazardous and suitable for use in environmentally sensitive locations and applications.

VerXan™ D gum is a highly dispersible powder that can be used for a variety of oilfield applications that use standard grade xanthan gum. VerXan™ D gum readily disperses and can be mixed into water under low shear conditions without the formation of lumps and “fisheyes” often seen with non-dispersible polymers, improving utility and efficiency.

In addition to its improved dispersibility, VerXan™ D gum has the typical properties of xanthan gum for oilfield use – excellent rheological control for water-based drilling, completion and work-over fluids in a wide range of brines.

Use for
