  • Chrome humates as drilling mud additives
    Patent number: 5191100
    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.
    Type: Grant
    Filed: February 8, 1985
    Date of Patent: March 2, 1993
    Assignee: Union Camp Corporation

  • Method and media for stimulating growth in foliage plants
    Patent number: 4566896
    Abstract: The disclosure is of a method for stimulating growth in a foliage plant. The method comprises potting the plant in a conventional potting medium to which there has been added a humate which was previously associated with a titanium sand deposit. The disclosure is also of improved potting mediums for foliage plants, which include titanium sand deposit derived humate.
    Type: Grant

  • Humate thinners for drilling fluids
    Patent number: 4311600
    Abstract: The disclosure is of the use of a particular humate to reduce the viscosity of water-based drilling fluids. The humate is usually found in association with titanium minerals and bears a unique compositional make-up. The composition is particularly advantageous as a drilling mud thinner, imparting high temperature stability to water-based drilling muds.
