Title: Innovations of Ralph S. Millhone

Introduction

Ralph S. Millhone is a notable inventor based in Brea, California, recognized for his contributions to the field of steam injection technology. With a total of six patents to his name, Millhone has made significant advancements that enhance the efficiency of steam injection wells.

Latest Patents

One of Millhone's latest patents focuses on steam injection profiling. This innovative method and apparatus improve the determination of injection profiles in steam injection wells. The process begins with measuring the mass flow rate of steam entering the well. A well logging tool is then utilized to measure temperature and/or pressure profiles within the perforated zone of the well. A liquid phase tracer is injected for a short duration into the well alongside the steam. The well logging tool, equipped with dual gamma ray detectors, measures the transit time of the tracer slug. In the preferred embodiment, the liquid tracer is either radioactive elemental iodine or sodium iodide. The procedure is repeated using a vapor phase tracer, which may include radioactive Krypton, Argon, or Xenon. By applying simple mass balance equations, a vapor and liquid profile can be calculated. Additionally, a spinner survey and a single tracer survey can be conducted to determine vapor and liquid rates, further refining the steam injection profiles.
