GUAR GUM
VISCOSIFIER
DESCRIPTION
GUAR GUM is a modified natural polymer specifically formulated for mixing a low solids biodegradable drilling fluid for use in water wells. GUAR GUM is a non-toxic free flowing powder that is completely biodegradable.
APPLICATIONS/FUNCTIONS
GUAR GUM 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 GUAR GUM fluid, AMC 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 GUAR GUM fluid followed by surging, will assist in optimum well production.
ADVANTAGES
- Readily dissolves
- Easily mixed in low shear environments
- Assists in filtrate reduction
- Reduces well bore pressure transmission in clays and shale
- Increases lubricity
- Physically plugs micropores
- Reduces hydraulic locking in ultramafics
- Controls irregular circulating pressures
- Improves core recovery and supports the borehole wall
- Reduces heaving and sloughing in poorly consolidated shales
- Reduces well bore swelling in conjunction with other inhibitors
- Used in brine, fresh and saline water
- Compatible with all other water-based products
RECOMMENDED TREATMENT
- 3 – 4kgs/m3 - Normal conditions
- 5 – 8kgs/m3 - Unconsolidated formations, coarse gravels
