Title: Innovations by Russel C. Hertzog

Introduction

Russel C. Hertzog is a notable inventor based in Ridgefield, Connecticut. He has made significant contributions to the field of logging apparatus and methods for determining elemental concentrations in subterranean formations. With a total of six patents to his name, Hertzog's work has advanced the technology used in geological exploration.

Latest Patents

Hertzog's latest patents include a logging apparatus and method for determining absolute elemental concentrations. This invention involves detecting first signals indicative of the absolute concentrations of elements in a rock matrix. The method utilizes high-energy neutrons to irradiate the formation and detect signals that indicate the relative concentrations of other elements. One of the key features of this invention is the ability to measure the absolute concentration of aluminum, which is then used to derive the concentrations of other elements. Additionally, he has developed a method and apparatus for determining borehole and formation constituents. This method employs a well-logging sonde to bombard the borehole contents and formation with fast neutrons, generating signals that reflect the composition of both.
