Patent number: 10605582Abstract: A tool for evaluating the internal surfaces of tubular is provided, wherein one or more arms extend outwardly from the tool to contact an inner wall surface of the tubular, and changes in the dimensions or condition of the inner wall result in changes in the position of the ends of the arms relative to the tool. This motion is converted, through an electromagnetic transducer. The probe arms extending from the tool are releasably held in bores formed by opposed members on the tool, within which the probe arms may pivot. The internal end of the probe arms need not be physically secured to an internal element of the tool, yet still enable motion of an internal components to actuate a transducer to provide electrical signals indicative of the tip of the probe arm relative to the tool as the tool traverses a tubular, such as a wellbore casing.Type: GrantFiled: April 29, 2016Date of Patent: March 31, 2020Assignee: PROBE HOLDINGS, INC.Inventors: Herve Ohmer, Monty D. Mayfield

Patent number: 9720127Abstract: A tool for evaluating the internal surfaces of tubular is provided, wherein one or more arms extend outwardly from the tool into contact with an inner wall of the tubular, and changes in the dimensions or condition of the inner wall result in changes in the position of the ends of the arms relative to the tool. This motion is converted, through an electromagnetic transducer, into an electrical signal, the accuracy of which deteriorates as the temperature of the tool changes. Calibration transducers are provided on the tool to provide correction factors to convert the electromagnetic transducer output into an accurate reading of the distance of the end of the arms from the tool thereby increasing the accuracy of the assessment of the inner wall of the tubular.Type: GrantFiled: May 1, 2015Date of Patent: August 1, 2017Assignee: Probe Holdings, Inc.Inventors: Herve Ohmer, Marvin Beckman, David Collart, Jason Penley, Juan Garibay

Patent number: 7637167Abstract: An apparatus (and corresponding method) for characterizing the fluid properties of a two phase fluid includes a restriction element (e.g., orifice plate or nozzle) along the flow path of the two phase fluid. At least one temperature sensor measures temperature of the two phase fluid flowing through the restriction element. A pressure sensor measures the pressure downstream of the restriction element. Time-of-flight measurements of pulses passing through the two phase fluid are made. The speed of sound within the two phase fluid is calculated from the time-of-flight measurements. At least one fluid property (e.g., a vapor phase fraction) of the two phase fluid is calculated from the measured pressure, the measured temperature, and the calculated speed of sound.Type: GrantFiled: April 25, 2008Date of Patent: December 29, 2009Assignee: Schlumberger Technology CorporationInventors: Franck Bruno Jean Monmont, Herve Ohmer, Gary Martin Oddie, Allan Peats
