Abstract
A method of analyzing a downhole fluid includes performing measurements of a dielectric property of the downhole fluid, the downhole fluid including a mixture of a filtrate fluid circulated through a borehole and a connate fluid. The measurements include a first measurement of the downhole fluid, and one or more additional measurements, each additional measurement performed after an amount of the filtrate fluid is injected into the downhole fluid to change the volume ratio, each additional measurement performed when the downhole fluid has a different volume ratio. The method also includes acquiring a plurality of reference profiles of respective reference mixtures, the respective reference mixtures including a first fluid and a reference fluid, comparing the measurements to each reference profile, and estimating a value of the dielectric property of the connate fluid based on the comparing.
