| Summary: | This invention relates to a non-aqueous fluid polymer suspension for use as a rheology modifier and fluid loss reducer in oil field applications. More particularly, this invention is directed to the use of an environmentally acceptable fluidized polymer suspension of cellulosic ethers and guar and its derivatives for use in oil field applications such as completion fluids, drilling fluids, fracturing fluids, stimulation fluids and oil well cement slurries.
This invention provides a water-free oil based fluid polymer suspension composition for use as a rheology modifier and fluid loss reducer in oil or gas well servicing fluids. It has been found that by using white medicinal oil as a carrier, high solids content and environmental friendly anhydrous fluidized polymer suspensions of xanthan gum, cellulose ethers, guar gum and derivatives thereof can be prepared. More specifically, in one aspect, an oil-based fluid polymer suspension (FPS) composition for use in oil or gas well servicing fluids is preferred containing:a) a hydrophilic polymer,b) an organophilic clay,c) a stabilizer, andd) a white medicinal oil having selected properties. |
