Latest Patents

Spencer holds a patent for a unique device titled "Pipe stress detection tool using magnetic Barkhausen noise." This innovative tool is designed to be disposable within a well pipe and serves a crucial function in detecting the freepoint of a well pipe. It incorporates an electromagnet that induces a magnetic field within the wall of the pipe, complemented by a Barkhausen noise sensing device. This device detects the magnetic Barkhausen noise generated in response to the induced magnetic field, allowing for the assessment of stress levels within the pipe. By performing two passes along the well pipe—one under less stress and another under greater stress—the tool compares outputs from both passes to accurately determine the location of the pipe's freepoint.
