3. Applications
As a nonionic polymeric viscosifier derived from natural Guar bean, HPG-I is of suitable substitution level,
good aqua-dissolvability / dispersibility, and high compatibility with anionic,
cationic and nonionic surfactant. With its good electrolyte tolerance, viscosity stability and good shear dilutability, HPG-I can be used in fracture fluids and drilling mud in oil field industry.
Fracture fluids are for the purpose to improve drill productivity and made by mixing HPG-I with water, cross-linker, polymerizing agent, and proppant.
The normal level of use in fracture fluids is 0.3-0.5% by weight.
HPG-I polymer can also be used in low-solids drilling fluids as a viscosifier and fluid-loss additive.
It will develop viscosity in both water and brine.
