Guar gum as a water-soluble polymer has found a broad range of applications in
the production of petroleum. It serves one or more functions, such as.
| |
-
Water-loss control
-
Viscosity control
-
Flocculation
-
Suspension
-
Turbulent friction reduction or mobility control
|
The use of guar gum as a suspending agent for sand in drilling mud and in
fracturing fluids led to the discovery that guar solutions have lower friction
than water. Guar has become a widely used material for both industrial and
experimental friction reduction because of the robust characteristics of its
molecule, which tend to prevent degradation due to high shear forces. When using
the optimum concentration, the horsepower required for the fracturing operation
is reduced by a factor of over five. |

Guar gum is used in froth flotation of postash as an auxiliary reagent,
depressing gangue minerals, which might be clay, talc, or shale. Guar gum is
also used as a flocculants (settling agent) to concentrate ores or tailings in
the mining industry. In practice, slimes and tailings from ore beneficiation
processes are concentrated so that the water can be reused and the solids easily
processed.
