- Greenbase™ Drispac® Polymer
Greenbase™ Drispac® Polymer

Drilling Specialties’ Greenbase™ Drispac® Polymer is a high performance polyanionic cellulose, suspended in a glycol ether base fluid.  The Greenbase™ Drispac® Polymer suspension is uniquely stable, easily handled and useful in both oilfield and non-oilfield applications.

Suspension Properties

Packaging

The Greenbase™ Drispac® Polymer is packaged in disposable pails, containing a net weight of 44 lbs of products (16 lbs of Greenbase™ Drispac® Polymer).

Drilling Specialties' Greenbase™ Drispac® Polymer will not experience the separation that is evident in other suspension products.  It is not subject to settling or fluid separation under normal storage or transport conditions.  Starting with a glycol ether and utilizing our unique suspension technology, we eliminate settling of the Drispac® Polymers 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.

Packaging the Greenbase™ Drispac® Polymer 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.

Environmental

Using EPA Method 1664, for a 40 PTG guar concentration in 1% KCl, the Greenbase™ Drispac® Polymer showed 19.6 ppm or less of total extractables.  There was no evidence of sheening.

The LC50, based on 96 hour range finder tests using Mysid shrimp (Mysidopsis bahia), was 1,000,000 ppm.  An MSDS for this product is available upon request.
