METHOD FOR ASSESSMENT OF PORE-THROAT SIZE DISTRIBUTION AND PERMEABILITY IN POROUS MEDIA

摘要

A computerized method and system include (a) estimating parameters that quantify rock fabric features (e.g., tortuosity, effective pore size, throat-size distribution) by joint interpretation of electrical resistivity, dielectric permittivity, and NMR measurements, (b) developing a new workflow for permeability assessment that incorporates the quantified rock fabric parameters, and (c) validating the reliability of the new permeability model in core-scale domain using electrical resistivity, dielectric permittivity, NMR, Mercury Injection Capillary Pressure (MICP), and permeability measurements.
