SYSTEM AND METHOD FOR ESTIMATING FILTRATE CONTAMINATION IN FORMATION FLUID SAMPLES USING REFRACTIVE INDEX |
摘要 |
A method and apparatus is described for estimating terminal purity or terminal contamination for a fluid during the withdrawal of the fluid from a subsurface formation. The apparatus and method provide for measuring refractive index of the fluid over a time period, fitting a curve through the refractive index measurements or data values derived therefrom and estimating a terminal refractive index or terminal value for the data values from the fitted to curve to estimate the terminal contamination or purity for the fluid. |
