Title: Innovations of John Justin Freeman

Introduction

John Justin Freeman is a notable inventor based in Pattison, Texas. He has made significant contributions to the field of rock characterization through his innovative methods. With a total of 10 patents to his name, Freeman's work has advanced the understanding of rock permeability and porosity.

Latest Patents

Freeman's latest patents include a method for digitally characterizing the permeability of rock. This invention provides a technique for estimating the permeability of rock from a digital image. A three-dimensional image of the rock is obtained and segmented, allowing for the determination of image permeability. Permeability correction factors are derived from the segmented image and a non-wetting liquid capillary pressure curve, which are then applied to obtain a corrected image permeability of the rock. Another significant patent is a method for characterizing the porosity of rock. This method also utilizes a three-dimensional image of the rock, from which image porosity is determined. A porosity correction parameter is obtained from a non-wetting liquid capillary pressure curve, which is then applied to achieve a corrected porosity of the rock.
