Title: Innovations of John C Reis in Steam Injection Profiling

Introduction

John C Reis is an accomplished inventor based in Yorba Linda, CA (US). He has made significant contributions to the field of steam injection profiling, holding 2 patents that enhance the efficiency and accuracy of steam injection wells. His work is particularly relevant in the oil and gas industry, where precise measurements are crucial for optimizing production.

Latest Patents

One of Reis's notable patents is an improved method and apparatus for determining injection profiles in a steam injection well. This innovative approach involves measuring the mass flow rate of steam entering the well. A well logging tool is utilized to measure temperature and/or pressure profiles within the perforated zone of the well. A liquid phase tracer is injected into the well alongside the steam for a short duration. 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 radioactive elemental iodine or sodium iodide. The process is then repeated with 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 combined to determine vapor and liquid rates, further refining steam injection profiles.
