Latest Patents
One of his latest patents is titled "Method and apparatus for improving the vertical resolution of NMR logs." This invention discloses a method and system for NMR echo-train data acquisition and processing, aimed at enhancing vertical resolution for a given signal-to-noise ratio. The method involves estimating non-formation signal components and removing them from the NMR signals. Additionally, it separates the functions of reducing coherent noise from random noise components to improve the resolution of NMR pulse echo data.
Another significant patent is the "System and method for clay typing using NMR-based porosity modeling." This invention characterizes formation properties based on NMR measurements, distinguishing between interstitial pore water and water adsorbed by clay minerals. It introduces a new petrophysical parameter called wetness clay, which is computed for members of the smectite group of clays, such as montmorillonite. The wet clay values enhance the quality and accuracy of overall log interpretation.
