Title: Innovations by Steven W. Powell
Introduction
Steven W. Powell is an accomplished inventor based in Houston, Texas. He holds two patents that showcase his expertise in developing innovative tools for the oil and gas industry. His work focuses on enhancing monitoring and surveying techniques within wellbores.
Latest Patents
One of his latest patents is a corrosion monitoring tool designed for monitoring corrosion levels within a wellbore. This tool is particularly suited for remote monitoring over extended periods. It utilizes a thin wall electrical resistance type corrosion sensor to determine the rate of metal loss within the wellbore. The corrosion sensor is preferably made of the same material as the production tubing or drill pipe of the well. It is positioned to allow the fluid within the wellbore to flow over the sensor at the same rate as the fluid flows over the tubing. A reference element is incorporated into the corrosion sensor to provide primary temperature compensation. Additionally, a temperature sensor provides temperature data and allows for secondary temperature compensation for the corrosion sensor. A central processing unit reads and stores the data from the three sensors into solid-state memory. The probe records data at programmable time intervals. Upon retrieval of the probe from the wellbore, it may be connected to a computer for downloading of the raw data and subsequent analysis.
Another significant invention is a borehole tool that utilizes a surface-activated multishot survey tool. This tool employs a dampened magnetic compass movably positioned within a probe to determine the direction of a borehole. Lamps in the probe are operable to light the face of the compass. A lens projects the image of the compass onto a movable film strip. An electrical cable is connected to the probe and is used to pass a current to the lamps, allowing for selective operation of the tool from the surface of the borehole. Electrical connectors are provided at each end of the probe so that it may be inverted within the borehole to accommodate surveys in which the angle of the borehole is greater than that at which the compass will operate without error. Because connectors are located at both ends of the probe, electrical current passes around the magnetic compass, creating a magnetic field about the compass. An alternating current is used to operate the tool, with the rate of change in direction of the current being faster than the movement response time of the dampened compass to the changing magnetic field generated by the current.
