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.
