Drilling Specialties’ Liquid Flowzan^® biopolymer is a high-purity xanthan gum biopolymer, suspended in an ultra-clean mineral oil. This type of polymer is unique when compared to most other polymers in oilfield drilling and completion applications. Xanthan gums are well known for their ability to provide extremely low-solids fluids with excellent carrying and suspending characteristics. This is due to their “shear thinning” properties. Fluids thickened with Flowzan^® biopolymer have a tendency to thin at higher velocities and thicken at lower velocities. This translates into the following:

• Optimized bit hydraulics resulting in higher penetration rates;

• Reduced circulating pressure losses;

• Improved hole cleaning with lower bentonite concentrations; and

• Minimal drilled solids settling under static conditions.

Liquid Flowzan^® biopolymer is a versatile product and can be used in most types of water-based fluids for rheology modification, hole cleaning and solids suspension. It provides excellent friction reduction for coiled tubing operations. It is useful over a wide pH range. Xanthan gum was the first truly stable thickener for hydrochloric acid used in the oilfield. The Liquid Flowzan^® biopolymer suspension is uniquely stable, easily handled and useful in both oilfield and non-oilfield applications.

Handling

For specific instructions on handling, refer to the MSDS.

Disposable pails, containing a net weight of 40 lbs of product (20 lb of Flowzan^® biopolymer). Other packaging options are available.

Environmental

Liquid Flowzan^® biopolymer is generally non-polluting and safe to handle.  The LC50 base 96-hour range finder tests using Mysid shrimp (Mysidopsis bahia), was 1,000,000 ppm.

Suspension Properties

Drilling Specialties’ 50% active Liquid Flowzan® biopolymer will not experience the separation that 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 xanthan 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. Liquid Flowzan® biopolymer 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 Flowzan® biopolymer 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.
