An equation has been developed to calculate effective gas permeability, k,. Unlike other permeability correlations, this equation implicitly takes into account the effective closure stress.
The interpretation of porosity, irreducible water saturation, and effective gas permeability from log data is generally based on equations that simulate laboratory measurements of these parameters.' In most of the permeability equations, the permeability is expressed as a function of porosity and irreducible water saturation.
In hydraulically fractured gas wells, the fracture conductivity dependence ...
