Accuracy of JBN Estimates of Relative Permeability: Part 2—Algorithms

Abstract

Abstract We develop algorithms that can be used for computer implementation of the Johnson, Bossier, and Naumann (JBN) method for estimating relative permeabilities from displacement experiments. The developed algorithms differ in the method used to calculate derivatives of measured data. The Monte Carlo error analysis developed in Part 1 of this paper (Pages 209–14) is used to evaluate the performance of the computer algorithms.
