| Greenbase™ Guar CM | |
|
Drilling Specialties’ Greenbase™ Guar CM is a pure, high-viscosity guar polymer, suspended in a glycol ether base fluid. The guar gum used in this product is carefully chosen to provide the highest solution viscosities possible with this type of polymer. The “CM” designation in the product name indicates that this polymer has been processed for use in continuous mix applications, where extremely fast hydration and subsequent viscosity development are required. This guar gum suspension is uniquely stable, easily handled and useful in both oilfield and non-oilfield applications. Suspension Properties Drilling Specialties’ 36% active Greenbase™ Guar CM will not experience the separation that is evident in other suspension products. It is not subject to settling or base fluid separation under normal storage or transport conditions. Starting with an environmentally friendly fluid and utilizing our unique suspension technology, we eliminate settling of the pure guar gum particles while the product remains fully pourable. The long-term stability of the suspension provides for consistent, reliable product properties at your field locations any place in the world.

Mixing Guar gum hydration is enhanced by adjusting the treating fluid pH to around 6. The rapid polymer hydration provides considerable versatility in allowing for either batch mix or continuous mix blending operations. The Greenbase™ Guar CM can be added into the mixing hopper, or metered directly in-line. Packaging Greenbase™ Guar CM is generally packaged in totes, containing a net weight of 4890 lb of product (1760 lb of guar gum). Other packaging options are available. | ||||||||||

Packaging the guar gum as a liquid suspension allows for accurate metering, and provides complete dispersion of the particles in your treating fluids before hydration begins. This quality eliminates problems of polymer lumping and incomplete viscosity development, even when facing adverse field mixing conditions. Hydration & Viscosity Development Greenbase™ Guar CM has been designed to provide easy dispersion and very rapid polymer hydration, specifically to satisfy the needs of continuous mix fracturing operations. When added to seawater, a KCl solution or other aqueous system, the guar gum suspension disperses readily without lumping, even under low shear conditions. Once dispersed, the gum hydrates very rapidly, generating most of its full viscosity within just a few minutes as shown in Figure 1. The rate of hydration can be further enhanced by increasing the shear conditions, or adding a surface tension reducer.
Greenbase™ Guar CM provides rapid development of very high fluid viscosity, as shown in Figure 2.
Applications
Technical Information
Environmental Information Using EPA Method 1664, for a 40 PTG guar concentration in 1% KCl, the Greenbase™ Guar CM showed 14 ppm or less of total extractables. There was no evidence of sheening. A 96-hour range finder test, using Mysid shrimp (Mysidopsis bahia), resulted in an LC50 of over 1,000,000 for the Greenbase™ Guar CM.
