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 12):
The system of  claim 1 , wherein the well comprises a steam injection well, wherein the one or more sensors generate output signals conveying information related to steam parameters including one or more of fluid velocity, temperature, pressure, or specific volume of the steam, and\n wherein the one or more processors are configured to:\n use a steam mass flow rate determination methodology based on the information in the sensor output signals from sensors located at a surface inlet of the well and a formation outlet of the well to determine a mass flow rate of steam flowing through the well at the inlet of the well and at the outlet of the well, and \n detect casing structural integrity events responsive to the mass flow rate at the surface inlet and the mass flow rate at the formation outlet not being substantially equal.
