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.

Abstract: Det er beskrevet en fremgangsmåte for å bestemme egenskaper ved et formasjonsfluid basert på målinger av fluidlydhastighet, en måling av fluiddensitet, eller begge deler. Egenskapene innbefatter kompressibilitet, termisk konduktivitet og gass/olje-forhold. Kompressibiliteten til et fluid er lik den resiproke verdien av produktet av lydhastig-heten i kvadrat og fluiddensiteten. Densiteten og lydhastigheten kan måles akustisk. Fremgangsmåten innbefatter videre en måte for å behandle data, innbefattende å anvende Savitzky/Golay-metoden og benytte en teknikk med variabel terskel.
