(54) Title: ANALYZER FOR A BLOWOUT PREVENTER W O 20 18/0 13077 Al (57) : A computing device can determine the integrity of a blowout preventer in a well system using a model generated from re- al-time sensor data. For example, the computing device can receive pre- determined values associated with how pressure decays or otherwise changes in a pressurization subsystem overtime. The pressurization sub- system can be for pressurizing the blowout preventer. The computing de- vice can also receive, from a pressure sensor, real-time pressure measure- ments indicating pressures in the pressurization subsystem. The comput- ing device can generate the model based on the predetermined values and the pressure measurements. The computing device can use the model to predict the pressure in the pressurization subsystem during a future pe- riod of time. The computing device can analyze aspects of the predicted pressure in the pressurization subsystem over the future period of time to determine if the blowout preventer is functioning properly.
