  • Method for measuring multiple parameters of drilling fluid
    Patent number: 11549910
    Abstract: A method and apparatus for measuring multiple parameters of drilling fluid using electric field perturbation, permittivity curves, time domain analysis and frequency domain analysis to identify constituents of drilling fluid and ratios of the drilling fluid constituents on a real time basis and to measure volumes and densities of the constituents on a real time basis.
    Type: Grant
    Filed: May 9, 2018
    Date of Patent: January 10, 2023
    Assignee: Mohr and Associates
    Inventors: Charles L. Mohr, Brandt C. Mohr, Benno Mohr, Michael Stordahl, James Van Corbach, Erik Von Reis, Christopher Mulkey, Ryan Sams, Kevin Dawes, Preston May, Duan Nguyen, Gordon Anderson, Dan Kenney, Bill Rausch, David Hurley
  • Method for identifying and characterizing a condensate entrained within a fluid
    Patent number: 11262323
    Abstract: A method for identifying and characterizing a condensate entrained in a fluid using time domain analysis and frequency domain analysis to identify individual volume fraction constituents and condensates within a pipe on a real time basis and to measure the volume of the individual volume fraction constituents and condensates flowing through the pipe on a real time basis.
