Biopolymer RXPT 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 Biopolymer RXPT have a tendency to thin at higher velocities and thicken at lower velocities.

Biopolymer RXPT  will not experience the separation, evident in other suspension products. It is not subject to particle settling or 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 Biopolymer RXPT 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. Biopolymer RXPT 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.

Application

Biopolymer RXPT is a versatile product and can be used in most types of water-based fluids for rheology modification, improved hole cleaning and solids suspension. It provides excellent friction reduction for coil 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. Our Biopolymer RXPT  is uniquely stable, easily handled and useful in both oilfield and non-oilfield applications.

Performance

The performance characteristics of the xanthan gums are well established in the oil field. Typical fluid properties imparted by Biopolymer RXPTare shown in Table 1. In fresh water and most brines, the xanthan gum produces stable viscosities as high as 275° F. In saturated salt water, that thermal stability has been shown to extend beyond 300° F. The addition of an oxygen scavenger may be useful in stabilizing the rheology at high temperatures.Biopolymer RXPT has been demonstrated to have a minimal effect on the permeability of Berea sandstone cores. For wellbore cleanup, however, the xanthan gum is acid soluble and is degradable by strong oxidizing agents.
