ENVIRONMENTALLY ACCEPTABLE FLUID POLYMER SUSPENSION FOR OIL FIELD SERVICES

摘要

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 derivaties 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; (d) a stabilizer; and (d) a white medicinal oil having selected properties.
