Downhole status detection using vibration

A method comprising:

• deploying, via a conveyance mechanism, a measurement tool downhole in a wellbore that includes a tubular therein;
• inducing, via a vibration-inducing device, vibration in the tubular;
• and
• detecting, via at least one interferometer coupled to the measurement tool, the vibration at a first location along an azimuth of the tubular to generate first data and detecting the vibration at a second location along the azimuth of the tubular to generate second data, wherein a first depth of the first location along the azimuth of the tubular is substantially equal to a second depth of the second location along the azimuth of the tubular, and wherein the first data and the second data are used to determine a status of the tubular or of a cement layer, the cement layer positioned between the tubular and a subterranean formation surrounding the wellbore, the status of the tubular being indicative of whether there is damage to the tubular, or the status of the cement layer being indicative of whether there is a strong bond between the cement layer and the tubular.

A system comprising:

• a processing device;
• and
• a memory device that includes instructions executed by the processing device for causing the processing device to perform operations comprising:
• receiving, by the processing device, first data associated with vibration at a first location along an azimuth of a tubular positioned in a wellbore, the vibration at the first location along the azimuth of the tubular detected by at least one interferometer coupled to a measurement tool, and the vibration in the tubular caused by a vibration-inducing device;
• receiving, by the processing second, second data associated with vibration at a second location along the azimuth of the tubular, the vibration at the second location along the azimuth of the tubular detected by the at least one interferometer coupled to the measurement tool, wherein a first depth of the first location along the azimuth of the tubular is substantially equal to a second depth of the second location along the azimuth of the tubular;
• determining, based on the first data and the second data, parameters associated with the tubular and a cement layer, the cement layer positioned between the tubular and a subterranean formation surrounding the wellbore;
• and
• determining, based on the parameters, a status of the tubular or a status of a cement layer, the status of the tubular being indicative of whether there is damage to the tubular, or the status of the cement layer being indicative of whether there is a strong bond between the cement layer and the tubular.
