Research in order to determine the most effective polymers as thickening agents in the compositions of water-based process fluids for workovers is accomplished and their optimal concentration is determined. The rheological properties and sand retention technology solutions, determined the effect of the polymer concentration and salinity.The pursued studies established that the most optimized polymers as thickeners for process fluids for workover are xanthan polymers . Xanthan polymer by Duo Vis is optimal for thickening of the process fluids on basis of fresh low-salt water, and for process fluids on basis of high-salt water it is xanthan polymer by Gammaksan. .
