XAN VIS 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. Shear-thinning fluids containing XAN VIS have low effective viscosities at the high shear rates encountered inside the drill string and at the bit. This low effective viscosity for minimal pressure losses and standpipe pressures allows optimized hydraulics and maximized rates of penetration. Conversely, at the low shear rates experienced in the annulus, XAN VIS enables the drilling fluid to have a high effective viscosity for adequately cleaning the well and suspending cuttings.

XAN VIS XD is a readily dispersible formulation of XAN VIS and recommended for use where mixing systems are inefficient or limited due to site restrictions. Readily Dispersible products will shear with limited mixing equipment. XAN VIS XD has very similar characteristics to XAN VIS and usage rates for each product are not expected to vary.
