DF dry polymers – based on a unique organosoluble gel structure – are designed to provide excellent fluid-loss control and low formation damage in oil and synthetic based fluids (OBM, SBM, drill-in fluids, completion fluids, etc) under HTHP conditions. The polymer particle morphology, solubility and crosslink density are optimized to make DF dry polymers very versatile and cost effective fluid-loss additives in a wide range of base fluids.
The ability of the micro-gel particles to deform under shear allows them to be easily and more efficiently back produced from the formation than currently used non-deformable fluid-loss additives, thus reducing risks of formation damage in the pay zone.
