Title: Innovations by Lawrence E McGowan
Introduction
Lawrence E McGowan is a notable inventor based in Bethel, CT (US). He has made significant contributions to the field of ultrasonic technology, particularly in applications related to borehole measurements. With a total of 3 patents, his work has advanced the understanding and capabilities of acoustic detection in geological settings.
Latest Patents
One of McGowan's latest patents focuses on measuring standoff and borehole geometry. This innovative method utilizes refracted ultrasonic waves to calculate tool standoff. An ultrasonic transmitter sends a wave toward the borehole wall at a critical incidence angle, allowing the refracted wave to travel along the wall and radiate energy back into the borehole. By measuring the travel time of this wave, McGowan's technique enables the calculation of standoff and the creation of two-dimensional and three-dimensional borehole geometry through repeated measurements at various azimuths.
Another significant patent addresses the acoustic detection of stress-induced mechanical damage in borehole walls. This method locates and measures mechanical damage in surrounding rock by detecting reductions in ultrasonic compressional wave velocity and focused acoustic energy. McGowan's approach includes various embodiments that utilize azimuthal ultrasonic compressional wave data to assess the integrity of the borehole wall.
