Title: George C Summerfield: Innovator in Borehole Logging Technology

Introduction

George C Summerfield is a notable inventor based in Ann Arbor, MI (US). He has made significant contributions to the field of borehole logging technology, particularly with his innovative methods for determining thermal neutron decay characteristics.

Latest Patents

Summerfield holds a patent for a "Thermal decay time logging method." This method involves a borehole logging technique that determines the thermal neutron decay characteristics of the formation surrounding the borehole. The process includes irradiating the formation with a burst of neutrons from within the borehole and detecting the concentration of diffusing thermal neutrons in at least three time gates following the burst. The corresponding count rate signals are produced in response to the detected neutrons. These signals are then combined in a predetermined manner to separate the thermal neutron decay rate characteristics from associated neutron diffusion characteristics. This method is repeated at different depth locations within the borehole, resulting in a recording of the rate of decay of thermal neutrons as a function of borehole depth.
