Title: Lisa L Pepin: Innovator in Petroleum Stream Analysis

Introduction

Lisa L Pepin is a notable inventor based in Sugar Land, TX (US). She has made significant contributions to the field of petroleum analysis, holding a total of 4 patents. Her innovative methods have advanced the understanding and analysis of petroleum streams, particularly in determining the composition of these complex mixtures.

Latest Patents

One of her latest patents is titled "Method for analyzing a petroleum stream." This invention provides methods for determining a solids to liquids ratio in a flowing petroleum stream that contains immiscible solids, oil, and water. The process involves directing microwave energy in the 10-12 Gigahertz range through the petroleum stream. The transmitted and reflected microwave energy is detected and compared to an empirically derived map of attenuated amplitude versus phase for reference petroleum streams with known solid, oil, and water contents. This comparison allows for the derivation of a solids to liquids ratio for the unknown stream.

Another significant patent is "Means and method for analyzing a petroleum stream." This invention includes a source of microwave energy and associated elements that deliver microwave energy to a petroleum stream. The circuitry receives microwave energy from the stream, and an electronic apparatus provides outputs utilizing the microwave energy and known values for 100 percent oil, gas, and water. By analyzing the readings of attenuation and phase shift, the proportions in the mix can be estimated through interpolation.
