transitional metal ions Carboxymethyl Hydroxypropyl Guar gum support sand 

Quick Detail:

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

Description:

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.

Applications:

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.

Specifications:

Appearance	Off white to pale yellow powder
Moisture	10% Max
Particle Size through us 120 mesh           through us 200 mesh	99% Min   90% Min
Viscosity (30℃,0.48% solution, 511 sˉ1)	34/36 cps Min
pH value	5.5-8.0/9.0-10.5
Carboxymethyl DS	0.1-0.3
Hydroxypropyl DS	0.1-0.3

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.
