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.

Patent number: 8746013Abstract: The invention relates to a burner module having a body that is either sintered or photo-cured, and to methods of making such a burner module. The body (110) of the burner (100) is formed from one of a sintered metal, a sintered alloy, a laminated glass ceramic, and a photo-cured polymer. 1 Sintering and photo-curing may be accomplished by irradiating the body with localized heating using a focused energy source, such as a laser. The burner module is resistant to thermal shock and provides a distributed, even stream of a precursor or precursors to be reacted in a flame of the burner module to form soot, which is to deposited on a receptor surface, and may be used for vapor and liquid precursor delivery systems. A soot deposition system having an array of such burner modules and methods of making a fused silica article by depositing soot using the burner modules are also described.Type: GrantFiled: March 25, 2008Date of Patent: June 10, 2014Assignee: Corning IncorporatedInventors: Muluwork Geremew, Daniel Warren Hawtof, Richard Curwood Peterson, Amy Lu Rovelstad, Christopher Clark Thompson

Patent number: 8390471Abstract: A system, method and device may be used to monitor conditions in a borehole. Energy is transmitted to a pulse generator located proximate a position to be interrogated with a sensor. The pulse generator stores the energy, then releases it in a pulse of electromagnetic energy, providing the energy to resonant circuits that incorporate the sensors. The resonant circuits modulate the electromagnetic energy and transmit the modulated energy so that it may be received and processed in order to obtain the desired measurements.Type: GrantFiled: September 7, 2007Date of Patent: March 5, 2013Assignee: Chevron U.S.A., Inc.Inventors: Don M Coates, M.
