Abstract

A method for characterizing a desired property of a fluid downhole comprises receiving an input signal representing sound speed of a fluid downhole, processing the input signal using a correlation equation expressing the desired property in terms of at least sound speed to produce an output signal representing the desired property, and outputting the output signal The correlation equation may be derived through a chemometnc analysis of a training data set comprising a plurality of input values and a plurality of output values derived from said input values In at least one example, the desired property is gas oil ratio.
