Anionic organic guar gum Viscosity 34 / 36 cps pH value 5.5

Anionic organic guar gum Viscosity 34 / 36 cps pH value 5.5-8.0 / 9.0-10.5

Quick Detail:

Carboxymethyl guar gum is an anionic carboxymethyl hydroxypropyl guar modified from guar gum.

Description:

1. Carboxymethyl hydroxypropyl guar gum is applied as a fracturing fluid in the recovery of oil and gas. It is a self-hydrating polymer, so no external buffer system is required to help viscosity development.

2. Viscosity build over time is dependent on pH, shear rates, and temperature. This polymer is a self-hydrating polymer; therefore, no external buffer systems are required to control viscosity development. This polymer also hydrates well at 40° F and 80° F, therefore performing well in cold environments. It is sensitive to salts, but will easily develop adequate viscosity to be functional. This polymer is alcohol tolerant and will viscosify a 50% solution MeOH.

Applications:

1. Put Carboxymethyl guar gum into the water with rapid agitation, adding at the point of greatest agitation. Viscosity will develop without adjusting solution Ph value.

2. As a stimulation fluid, this polymer exhibits good thermal stability and can be cross-linked with a number of transitional metal ions, including borates. Typically, if crosslinking the carboxyl group,an aluminum complexing agent is suggested. This polymer exhibits excellent carrying capacity to support sand or other proppants.

Specifications:

Competitive Advantage:

As a stimulation fluid, carboxymethyl hydroxypropyl guar gum has good thermal stability and can be cross-linked with a number of transitional metal ions. With its excellent carrying capacity, carboxymethyl hydroxypropyl guar gum can support sand or other prop-pants, and it is alcohol tolerant while it is kind of sensitive to salts.
