Abstract:
    The disclosure is of the use of chrome humate derivatives to reduce the viscosity of and/or to prevent fluid loss in water-based drilling fluids. The composition is much more effective as a drilling mud thinner, and as a fluid loss control agent than the commercially available ferrochrome lignosulfonate, chrome lignite or humate compositions.
