BIO-VIS
VISCOSIFIER
DESCRIPTION
BIO-VIS is a modified natural polymer specifically formulated for mixing a low solids biodegradable drilling fluid for use in water wells. BIO-VIS is a non-toxic free flowing powder that is completely biodegradable.
APPLICATIONS/FUNCTIONS
BIO-VIS provides excellent viscosity and filtration control in fresh and salty water and makes a complete mud system. This low solids polymer system breaks down naturally and eliminates mudding of water aquifers which frequently occurs when using bentonite as a mud additive.
To extend the life expectancy of a BIO-VIS fluid, BIOCIDE should be added to prevent fermentation. To accelerate the development of a well, SODIUM HYPERCHLORITE solution can be added. The addition
of 10 litres of SODIUM HYPERCHLORITE per 1000 litres
of BIO-VIS fluid followed by surging, will assist in optimum
well production.
RECOMMENDED TREATMENT
- 3 - 4kg/m3 - Normal conditions
- 5 - 8kg/m3 - Unconsolidated formations, coarse gravels
