  • Method for identifying and characterizing hydraulic units of saturated porous media: tri-kappa zoning process
    Patent number: 5193059
    Abstract: The present invention is a method of logging a formation for permeability using a logging tool that is calibrated to dynamically correlate macroscopic porosity measurements to microscopic permeability measurements for the formation. The correlation is determined from hydraulic unit characterization factors which are calculated from parameters of the formation determined in an analysis of core material taken from the hydraulic units determined to be in the geologic units. The hydraulic units are identified from the relationship of direct permeability and porosity measurements with calculated hydraulic unit characterization factors for the formation.
