HYDRO-ZAN T is a technical grade non dispersible high molecular weight biopolymer used for increasing the rheological parameters in water-based drilling fluids. Small quantities provide excellent viscosity for suspending weighting material for all water-based drilling fluids systems. HYDRO-ZAN T produces a fluid that is highly shear-thinning and develops a true gel structure.
SOLUBILITY IN WATER
Cream to tan
HYDRO-ZAN T provides an optimised rheological profile with elevated low-shear-rate viscosity (LSRV) and shear thinning characteristics with low “n” values. This results in fluids with inverted flow properties, low effective viscosity for minimal pressure losses and standpipe pressure. HYDRO-ZAN T delivers optimum hydraulics with maximised rates of penetration and at the low-shear-rate experienced in the annulus enables the fluid to have a high effective viscosity for adequately cleaning of the well and suspend cuttings.
Provides shear-thinning rheology for improved hydraulics.
Easy to mix.
Viscous laminar flow in the annulus for improved well-bore stability with maximum hole-cleaning and suspension capacity.
The normal application is from 0.25 - 2.5 lb/bbl (0.71 – 7.1 kg/m3). For special applications, such as difficult hole cleaning, concentrations of up to 4 lb/bbl (11.4 kg/m3) may be required.
Effective up to 250 0F (121 0C). Above this temperature include oxygen scavengers in the formulation.
Efficacy is reduced in high salinity environments.
Needs shear and temperature to fully yield.
Subject to bacterial degradation – use of a biocide is recommended
Consult MSDS before use and use personal protective equipment as advised.
HYDRO-ZAN T is packaged in 25 kg (55.1 lb) multi-wall, paper sacks. Store in a dry location away from sources of heat or ignition.
