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.

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.

Abstract: A method for detecting an operational condition of a multi-conductor cable is described, and which includes generating a first, single ended, time domain reflectometer signal which is introduced into a multi-conductor cable; processing the first, single ended, time domain reflectometer signal so as to generate a first, differential time domain reflectometer signal; supplying the first, differential time domain reflectometer signal to the multi-conductor cable; converting a reflected, differential time domain reflectometer signal into a second, single ended, time domain reflectometer signal; numerically and/or graphically analyzing the second, single ended, time domain reflectometer signal; and identifying, by the numerical and/or graphical analysis, an operational condition of the multi-conductor cable undergoing the testing.
