- Liquid Drispac® Polymer
Liquid Drispac® Polymer
Liquid Drispac® Polymer is a high performance polyanionic cellulose, suspended in an ultra-clean mineral oil. The Liquid Drispac® suspension is uniquely stable, easily handled and useful in both oilfield and non-oilfield applications.

Drilling Specialties' 40% Liquid Drispac® Polymer will not experience the separation, which is evident in other suspension products.  It is not subject to settling or oil separation under normal storage or transport conditions.  Starting with a fine grade mineral oil and utilizing our unique suspension technology, we eliminate settling of the Drispac® Polymer 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.  Liquid Drispac® Polymer has seen successful application in both warm climates, like the Gulf of Mexico and the Middle East, and in cold climates, like the North Sea and Alaska.

Packaging the 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.

Advantages

 Performance

The performance characteristics of Drispac® Polymer are well established in the oilfield.  As a liquid suspension, this polymer disperses in water and develops viscosity very quickly.

Environmental

The LC50, based on 96 hour range finder tests using Mysid shrimp (Mysidopsis bahia), was 1,000,000 ppm.  The  Liquid Drispac® Polymer passed the sheen test in both fresh water and seawater.  

Handling

For specific instructions on handling, refer to the MSDS.

Packaging

Disposable pails, containing a net weight of 40 lbs of product (16 lbs of Drispac® Polymer)
