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.
COMMON NAME
Xanthan Gum
SOLUBILITY IN WATER
Soluble
APPEARANCE
Powder
SPECIFIC GRAVITY
1.5 -1.7
COLOUR
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.
􀂾 Effective viscosifier.
􀂾 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.
