Hydroxypropyl guar gum (HPG) is modified from guar gum. It is one new kind agents and low harm to land. It is widely used in oil well drilling due to its multi-function such as water loss control, viscosity control, friction reduction, lubrication and cooling of the drill bits. In explosives Guar improves resistance to water and aging in explosives gels. Gum gum when used with transition metal ions, increases viscosity. It also works as a thickening agent in blasting slurry and for explosive mixture. HPG is mainly used in fracturing fluid and drilling mud. Compared with Guar Gum, HPG has far less water-insoluble and acid-insoluble matter with the properties of easier solubility and degradation.
