Abstract
A wellhead landing, locking and sealing detection system may receive an acoustic signal from at least one acoustic sensor located on an outer surface of a wellhead. A wellhead landing, locking and sealing detection system may process the acoustic signal resulting in a processed acoustic signal. Processing the acoustic signal may include normalizing the acoustic signal, smoothing the acoustic signal, and differentiating a background signal from the acoustic signal. A wellhead landing, locking and sealing detection system may select a portion of the processed acoustic signal. A wellhead landing, locking and sealing detection system may identify a reflection characterization, frequency or profile from the portion. A wellhead landing, locking and sealing detection system may, based on the reflection characterization, frequency or profile, identifying a landing, locking and sealing configuration of the equipment with the wellhead.
