OSTI ID:6886913
Cores and logs used in the study were from a Department of Energy well in Oldham County containing a wide range of separate-vug porosity in a simple upward-shoaling carbonate sequence of early Permian (Wolfcampian) age. The authors investigated two wireline methods, one involving acoustic logs and one involving resistivity logs, and both were found to determine separate-vug porosity. Two equations relating interparticle porosity and permeability were derived using the general relationship between particle size, interparticle porosity, and permeability described earlier by Lucia as a guide to define porosity-permeability relationships. The authors report that permeabilities calculated using particle-size and interparticle porosity determined by subtracting separate-vug porosity from total porosity are more accurate than those calculated from total porosity data alone.
