Abstract
A method (and corresponding downhole tool) is provided for downhole fluid analysis of formation fluids. The downhole tool is operated to draw live fluid from the formation through the downhole tool and acquire observed sensor measurements of the live fluid (which includes filtrate contamination) that flows through the downhole tool. The observed sensor measurements are used in an inversion process that solves for a set of input parameter values of a computational model that predicts level of filtrate contamination in the live fluid that flows through the downhole tool. The set of input parameter values includes at least one endpoint value for the observed sensor measurements. The set of input parameter values solved by the inversion process can be stored and output for different applications.
