Emmanuel O. Udegbunam 1998 <p>An improved method determines vuggy carbonate permeability on the basis of specific surface area per unit pore volume and a flow zone indicator (FZI). Comparisons of fit standard error estimates show that this approach is superior to the multivariable empirical correlations of Chilingarian, et al., and to the ANN-estimated permeabilities. </p> application/pdf en PennWell Corporation Method determines vuggy carbonate permeability article
