  • Method of making a drilling fluid containing carbon black in a dispersed state
    Patent number: 5114597
    Abstract: A process for the manufacture of a water based drilling fluid additive comprising the steps of: (a) mixing hydrophobic carbon black and either a surfactant or a dispersant and (b) shearing the mixture of step (a) under a sufficiently high mechanical shear for a sufficient time to convert the hydrophobic carbon black into hydrophilic carbon black. This invention is also directed to a water based drilling fluid additive prepared according to the above process and the use of the additive in a water based drilling fluid.
    Type: Grant
    Filed: February 22, 1990
    Date of Patent: May 19, 1992
    Assignee: Sun Drilling Products Corporation
    Inventors: Jerry J. Rayborn, J. Phillip Dickerson
  • Method of making drilling fluid containing asphaltite in a dispersed state
    Patent number: 5114598
    Abstract: A process for the manufacture of a water based drilling fluid additive comprising the steps of:(a) premixing hydrophobic asphaltite and either a surfactant or a dispersant and(b) shearing the mixture of step (a) under a sufficiently high mechanical shear for a sufficient time to convert the hydrophobic asphaltite into hydrophilic asphaltite. This invention is also directed to a water based drilling fluid additive prepared according to the above process and the use of the additive in a water based drilling fluid.
