Hydroxypropyl Guar Application
It is a kind of advanced non – ionic thickener with good dispersive solubility in water. Mainly used in oil field fracturing fluid and drilling mud. Hydroxypropyl Guar gum is prepared into a solution, mixed with crosslinking agent and proppant to produce fracturing fluid, which can be used in oilfield fracturing to improve oil production. The addition of hydroxypropyl Guar gum in drilling mud generally keeps water and lubricates, reduces the mud’s water loss, and alleviates the formation damage Pollution.
