A Bayesian Methodology for Estimating Relative Permeability Curves

Abstract

Summary Among the various properties important for simulating reservoir behavior, relative permeability curves may be the most poorly determined by current methods. This paper presents a method for obtaining improved estimates of relative permeability curves. A Bayesian-type performance index is used to incorporate prior estimates of relative permeability curves into an automatic history-matching algorithm. Estimates obtained with the method are consistent with the reservoir production and yet conform to the prior estimates.
