Title: Eric C. Hopkinson: Innovator in Well Logging Technology

Introduction

Eric C. Hopkinson is a notable inventor based in Houston, TX (US), recognized for his contributions to the field of well logging technology. With a total of 5 patents to his name, he has made significant advancements that enhance the efficiency and accuracy of geological assessments.

Latest Patents

Among his latest patents is the "Method and apparatus for induced gamma ray logging." This invention involves a neutron-induced gamma ray well logging instrument where a neutron generator is pulsed at a preselected clock frequency. Each neutron burst produces inelastic scattering gamma rays and capture gamma rays. The inelastic scattering gamma rays are detected using a bismuth germanate scintillator during a first time interval when the neutron source is active. Capture gamma rays are detected during a subsequent interval after each neutron burst. The detected pulses are converted into electrical pulses by a photomultiplier and processed to measure the characteristic full-energy photopeaks of selected elements within geological formations.

Another significant patent is the "Method and apparatus for measuring neutron characteristics of material." This invention utilizes a pulsed source of fast neutrons and a radiation detector system in a well logging instrument. The detector responds to the thermal neutron population decay rate, allowing for the measurement of the macroscopic neutron absorption cross-section (Sigma) of surrounding formations. The Sigma log is a composite of two measurements, providing valuable data for geological analysis.
