Patent number: 10072494Abstract: A system for determining a characteristic of an oil well includes a signal source to generate an excitation signal during a first time duration and to generate a local oscillator signal during a second time duration. The system further includes a directional coupler, and a resonator disposed in an annulus of an oil well to receive the excitation signal through the directional coupler. The system also includes a mixer to receive a resonator signal from the resonator through the directional coupler, to receive the local oscillator signal, and to generate a mixer output signal based on the resonator signal and the local oscillator signal. The system further includes a filter to filter the mixer output signal to produce an intermediate frequency signal having an intermediate frequency, and a processor to determine a pressure or a temperature experienced by the resonator based on the intermediate frequency signal and the excitation signal.Type: GrantFiled: November 24, 2015Date of Patent: September 11, 2018Assignee: CHEVRON U.S.A.

Patent number: 9360384Abstract: A pressure sensor for sensing a pressure of a fluid includes a Bourdon tube that has a helical segment and an anvil. A portion of the anvil is positioned within the helical segment. The sensor also includes a dielectric material positioned between the portion of the anvil and the helical segment. The anvil, the dielectric material, and the helical segment form a variable capacitor. A capacitance of the variable capacitor changes based on a pressure applied to the Bourdon tube.Type: GrantFiled: February 14, 2014Date of Patent: June 7, 2016Assignee: CHEVRON U.S.A.

Patent number: 9316063Abstract: A system for applying power into a wellbore. The system can include a casing, a tubing string, a first and second isolator sub, a power source, and an electrical device. The casing has a first cavity running therethrough. The tubing string is disposed within the first cavity without contacting the casing, where the tubing string has a second cavity running therethrough. The first isolator sub is mechanically coupled to the tubing string and positioned between the neutral section and the power-transmitting section of the tubing string. The power source is electrically coupled to the power-transmitting section of the tubing string below the first isolator sub. The second isolator sub is mechanically coupled to the tubing string and positioned between the bottom neutral section and the power-transmitting section of the tubing string. The electrical device is electrically coupled to a bottom end of the power-transmitting section of the tubing string.Type: GrantFiled: March 14, 2013Date of Patent: April 19, 2016Assignee: CHEVRON U.S.A.

Publication number: 20160003027Abstract: This disclosure relates to a system and method for detecting structural integrity of a well casing. The system may detect casing structural integrity events. The casing structural integrity events may include structural failures of the casing and/or potential structural failures of the casing. The well casing may be drilled and/or otherwise embedded into a geologic structure. The well casing may be subject to geologic forces generated by the geologic structure. Unplanned and/or unexpected forces and/or movement may pose a risk to the structural integrity of the casing. Forces and/or movement of sufficient magnitude may result in damage to and/or destruction of the casing. Damage to and/or destruction of the casing may cause a loss of the natural resources being extracted via the well associated with the well casing, contamination of areas surrounding the well, undesirable surface expression, and/or other negative effects.Type: ApplicationFiled: March 12, 2014Publication date: January 7, 2016Applicant: Chevron U.S.A.

Patent number: 9103198Abstract: A system, method and device may be used to monitor conditions in a borehole. Well tubing and casing act as a conductive pair for delivering power to one or more downhole active sensors. At the surface, power and signal are isolated so that the same conductive pair may act to transmit the sensor signals to the surface. In an embodiment, the sensor signals are RF signals and the surface electronics demodulate the RF signals from the sensor power.Type: GrantFiled: November 17, 2014Date of Patent: August 11, 2015Assignee: CHEVRON U.S.A.

Patent number: 8844362Abstract: A pressure sensor for sensing pressure of a fluid includes a tubular housing that has a first capacitor plate segment and a second capacitor plate segment. Each of the first capacitor plate segment and the second capacitor plate segment includes a respective substantially planar inner surface. The pressure sensor also includes an anvil positioned within the tubular housing. The anvil and the tubular housing function as opposite terminals of a variable capacitor. A first capacitor plate side of the anvil and the first capacitor plate segment face each other and have a first gap therebetween. A second capacitor plate side of the anvil and the second capacitor plate segment face each other and have a second gap therebetween. Capacitance of the variable capacitor changes in response to a first change in a size of the first gap and a second change in a size of the second gap.Type: GrantFiled: August 16, 2013Date of Patent: September 30, 2014Assignee: Chevron U.S.A.
