Title: Innovations of George R Coates in Gas Detection Technology

Introduction

George R Coates is a notable inventor based in Austin, TX, who has made significant contributions to the field of gas detection technology. With a total of six patents to his name, Coates has developed innovative systems that enhance the detection and estimation of hydrocarbons in the near wellbore zone.

Latest Patents

Coates' latest patents include a groundbreaking system and method for lithology-independent gas detection using multifrequency gradient NMR logging. This well logging system is designed to detect the presence and estimate the quantity of gaseous and liquid hydrocarbons. The system employs a gradient-based, multiple-frequency NMR logging tool to extract signal components that are characteristic of each type of hydrocarbon. A new data acquisition method is proposed, where measurements at different frequencies are interleaved. This allows for the collection of multiple data streams in a single logging pass, corresponding to different recovery times and diffusivity for the same spot in the formation. The processed data streams enable the determination of mineralogy-independent water and hydrocarbon saturations, as well as porosity estimates. The accurate estimates of gas and oil saturations are crucial for assessing water content, permeability, and other important parameters.
