  • Method of using biologically-derived monoesters as drilling fluids
    Patent number: 9115556
    Abstract: The present invention is directed to the method drilling a borehole with monoester-based drilling fluid compositions. In some embodiments, the methods for making such monoester-based lubricants utilize a biomass precursor and/or low value Fischer-Tropsch (FT) olefins and/or alcohols so as to produce high value monoester-based drilling fluids. In some embodiments, such monoester-based drilling fluids are derived from FT olefins and fatty acids. The fatty acids can be from a bio-based source (i.e., biomass, renewable source) or can be derived from FT alcohols via oxidation.
    Type: Grant
    Filed: August 22, 2013
    Date of Patent: August 25, 2015
    Assignee: Chevron U.S.A. Inc.
    Inventors: Stephen Joseph Miller, Saleh Ali Elomari, Edward Malachosky, Edward Keith Morton, Ronald John Lenz, Jr., Rithana Chea
  • Biologically-derived monoesters as drilling fluids
    Patent number: 9115303
