Abstract

En fremgangsmåte og en anordning er beskrevet for å estimere sluttrenheten eller sluttforurensningen for et fluid under uttrekking av fluidet fra en undergrunnsformasjon. Anordningen og fremgangsmåten er innrettet for måling av brytningsindeksen til fluidet over en tidsperiode, tilpasning av en kurve gjennom brytningsindeksmålingene eller dataverdier utledet fra disse, og estimering av en sluttbrytningsindeks eller sluttverdi for dataverdiene fra den tilpassede kurven for å estimere sluttforurensningen eller sluttrenheten til fluidet.A method and apparatus are described for estimating the final purity or final contamination of a fluid during extraction of the fluid from a subsurface formation. The apparatus and method are adapted for measuring the refractive index of the fluid over a period of time, adapting a curve through the refractive index measurements or data values derived therefrom, and estimating a final refractive index or final value of the data values from the custom curve to estimate the final contamination or final unit.
