Use of simple core data to model permeability.
Many models have been proposed and developed over the last 50 years or more linking permeability to mercury porosimetry (injection) data. In most cases these models are empirical and worse apply only in specific lithology’s, formations or reservoirs.
A new method has been developed which combines core electrical measurements and mercury injection data – both of which are virtually standard components of most special core analysis programs. A detailed analysis of the method has shown it to be theoretically robust and indeed show a fundamental link between the Archie equation and permeability.
