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.

Abstract: A centralizer for use in high speed rotor dynamics applications includes a housing having a first end portion and a second end portion. The centralizer further includes a rotatable shaft positioned within a cavity of the housing. The centralizer also includes flexure springs that are each attached to and extend between the first end portion and the second end portion. The flexure springs are compressible toward a middle portion of the housing that is between the first end portion and the second end portion. The centralizer further includes roller wheels attached to the flexure springs.
