Title: The Innovative Contributions of David S. Chan
Introduction
David S. Chan is a notable inventor based in Bethel, Connecticut, who has made significant contributions to the field of borehole technology. With a total of four patents to his name, Chan's work focuses on enhancing the methods and apparatuses used in borehole investigations.
Latest Patents
One of Chan's latest patents is titled "Method and apparatus for producing an image log of a wall of a borehole." This innovative technique involves using a high-resolution tool equipped with sensors to measure characteristics such as the conductivity of the borehole wall. The tool's design allows for circumferential overlapping measurements, which are then processed to create a linear depth display free from visually detectable artifacts. The resulting image log showcases variable intensity images, highlighting small-scale variations and significant features effectively.
Another important patent by Chan is the "Method and apparatus for measuring the depth of a tool in a borehole." This invention describes a high-resolution method for determining the depth of a tool suspended from a cable within a borehole. By utilizing accelerometers to measure the tool's acceleration and combining this data with cable depth measurements, Chan's method employs a Kalman filter to provide continuous estimates of the tool's velocity and depth. The system is designed to adapt during discontinuous motions, ensuring accurate measurements even when the tool experiences sticking.
