Abstract: A method is described for lithofacies classification including receiving well logs representative of a subsurface volume of interest; deriving lithofacies from the well logs based on lithofacies cutoffs; calculating thickness of individual beds of the lithofacies; defining thickness thresholds based on the thickness of individual beds; upscaling to filter thin beds from thick beds based on the thickness thresholds; and classifying lithofacies intervals based on the upscaling. The method may be executed by a computer system.
