Abstract:
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.

Claim (Index 13):
A method for detecting structural integrity of a well casing in a well with a detection system, the well comprising a wellhead at a ground surface of the well, above ground extraction equipment located at or near the wellhead, the extraction equipment configured to extract liquid and/or gas from an underground reservoir through the wellhead, a conductive well casing configured to surround conductive well tubing, the tubing being configured to communicate the liquid and/or gas from the underground reservoir to the above ground extraction equipment, the casing being embedded in a geologic structure, and a hanger coupled to the wellhead, the hanger configured to suspend the tubing within the casing, the system comprising one or more sensors, and one or more processors, the method comprising:\n coupling the one or more sensors to one or more of the extraction equipment, the wellhead, the hanger, the tubing, or the casing; generating, with the one or more sensors, output signals conveying information related to a structural integrity of the casing and/or a casing-tubing pair, the information related to the structural integrity of the casing and/or the casing-tubing pair comprising information indicating a response of the tubing, the casing, the liquid, and/or the gas of the well to a stimulus generated for the well; detecting, with the one or more processors, casing structural integrity events based on the output signals, and generating casing structural integrity event notifications that correspond to the detected casing structural integrity events for delivery to a user, the casing structural integrity events including one or both of structural failures of the casing or potential structural failures of the casing.
