Guar is also known as Cluster Bean (cyamopsis Tetragonoloba) a drought hardly leguminous crop. Guar is being grown for seed, green fodder, vegetable and green manuring. It is an annual plant about 4 feet high, vertically stacked, large leaves and clusters of pods. The pods are used as a green vegetable or as a cattle feed besides the industrial extraction of Guar gum.
Properties of Guar Gum
- It is soluble in cold water.
- It has strong hydrogen bonding properties.
- It has excellent thickening, emulsion, stabilizing and film forming properties.
- It has excellent stability to control rheology by water phase management.
Guar Gum is used as:
- Natural thickener
- Bonding agent
- Gelling agent
- Natural Fiber
- Fracturing agent
The natural fast hydrating, dispersible and diesel slurriable guar gum is ideally suitable for all rheological requirements of oil well drilling, continuous fracturing and diesel slurry. It is widely used in oil well drilling due to its multi-function such as fluid and water loss control, viscosity control, lubrication. It is used for cooling of drill bits, mud drilling and cementing slurries, where immediate high viscosity and quick hydration is required.
The main use of guar gum is in top hole oil well drilling. Industrial grade guar gum powder is suitable for use in oil well fracturing, oil well stimulation, mud drilling and serves as a stabilizer, thickener and suspending agent.
In oil well drilling guar gum used as a surfactant, fracturing fluid and synthetic polymer for all requirements of water based and brine based oil well drills. It attains high viscosity in 3 to 5 minutes of time.
Fast Hydrating Slurriable Guar
The natural fast hydrating and slurriable guar is a non ionic guar, polymeric viscosifier that is slurrible up to 50 percent of solids in systems such as diesel fuel. In aqueous systems, its main use is in the stimulation of oil and gas wells as a fracturing fluid. This yields excellent pump ability, good hydration, good thermal stability and excellent shell life. It can be typically cross linked with borates and once cross linked it exhibits excellent carrying capacity to support sand or other proppants to be placed in the created fracture. The viscosity of hydrating slurriable guar can be reduced or broken by using enzymes, oxidizers or acids such as HCL.
Guar Gum in Oil Field Applications
Industrial grade Guar gum powder are use in oil well fracturing, oil well stimulation, mud drilling and industrial applications and preparations as a stabilizer, thickener and suspending agent.
It is a natural, fast hydrating dispersible guar gum and is diesel slurriable.
In the oil field industry, guar gum is used as a surfactant, synthetic polymer and deformer ideally suited for all rheological requirements of water-based and brine-based drilling fluids.
High viscosity Guar Gum products are used as drilling aids in oil well drilling, geological drilling and water drilling.
These products are used as viscosifiers to maintain drilling mud viscosities that enable drilling fluids to remove drill waste from deep holes.
Guar gum products also reduce friction in the holes, and so minimising power requirements. Some Guar Gum products act to minimise water loss should occur in broken geological formations.
