Title: Innovations by Thomas L. Stewart

Introduction

Thomas L. Stewart is a notable inventor based in Houston, TX, with a remarkable portfolio of 12 patents. His work primarily focuses on enhancing safety and efficiency in the oil and gas industry. Stewart's innovative solutions have made significant contributions to pipeline monitoring and oil analysis.

Latest Patents

One of Stewart's latest patents involves third-party detection around pipelines. This invention utilizes geophones placed around pipelines to detect the presence of third parties, such as heavy construction vehicles. The associated computer equipment acquires data from the geophones and discriminates frequencies linked to heavy construction activities. Another significant patent is the in situ BS&W measurement, which features a centrifugal filter element inserted into a pipeline to provide a dry oil stream for analysis. A moisture sensing probe is positioned along the central axis of the centrifugal filter to sense the properties of the dry oil stream. Additionally, a second probe is inserted into the pipeline to measure the properties of the undried oil. By comparing the outputs of the two probes, the water content of the oil in the pipeline can be accurately determined.
