Permeability Estimation Using Porosity Logs and Rock Fabric Stratigraphy: An Example from the Sacroc (Pennsylvanian) Field, Scurry County, Texas

F. Jerry Lucia, Charles Kerans

Abstract

Estimating permeability from porosity logs has been a major problem in carbonate reservoirs. The rock-fabric method of calculating permeability from wireline logs uses the global transform equation, which requires interparticle porosity and rock-fabric number. A method has been developed that uses rock-fabric stratigraphy to obtain an apparent rock-fabric number and total porosity rather than interparticle porosity. These values are used as input into the global transform to estimate permeability.
