XAN-STAR D is a biopolymer used for increasing viscosity in water-base systems. Small additions provide viscosity and weight-material suspension for all water-base mud systems.

XAN-STAR D has the unique ability to produce a fluid that is highly shear-thinning (LSRV).


XAN-STAR D effectively increases viscosity for cuttings transport and suspension in all water-base fluids, from highly weighted to low-solids systems, and including freshwater, seawater, salt and heavy-brine systems.
