Pregelatinized starch is extensively used as an additive to prevent the seepage of soil filtrates into the wells by increasing the viscosity of the drilling mud and reducing the fluid loss by sealing the walls of the borehole. our Pregelatinized starch helps drills reach further and run freely, control fluid loss, provide temperature stability and maximize solids removal and hydraulic efficiency.It is a Non-ionic natural polymer and highly effective in all waters including fresh-, sea, saturated salt water, calcium chloride or potassium chloride or any other brine based system. High quality biocide added to resist against bacterial and enzymatic degradation.
