Patent abstract

A method of determining properties of a formation fluid based on measurements of fluid sound speed, a measurement of fluid density, or both. The properties include compressibility, thermal conductivity, and gas oil ratio. The compressibility of a fluid is equal to the reciprocal of the product of the sound speed squared and fluid density. The density and the sound speed can be measured acoustically. The method further includes a manner of processing data including applying the Savitzky-Golay method and utilizing a variable thresholding technique.
