<p>Managing operation of a sealing element is described. In some aspects, failure of the sealing element of a pressure drilling system may be predicted. Deformation of the sealing element as a tool joint is pulled through the sealing element may be detected and tracked 400 to determine if a deformation pattern of sealing element changes. Responses of sealing element due to one or more of stress, strain, temperature, mechanical load, and pressure using a network of sensors around sealing element can be detected. Responses 402 may be tracked 404 over time. Detected responses are compared 406 to tracked responses to identify changes in the symmetry of responses over time or changes in magnitude of responses over time. Changes are associated with fractures occurring within sealing element. A remaining life of sealing element is predicted 408 based on the changes and replacement may be scheduled 410 based at least in part on the predicted remaining life.</p> |
