  • 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.
