Abstract: A computer implemented method of predicting a future maintenance event of a pumping equipment on a wellbore pumping unit comprising loading a pump usage log and a pump maintenance log into a predictive maintenance model. The predictive maintenance model is trained by a machine learning process with a historical database of completed pumping jobs. The predictive maintenance model determines a probability of a future maintenance event in response to the current pump usage. The unit controller displays an alert of the remaining pump life in comparison to a threshold value for a recommended pump maintenance period or a required pump maintenance period.

Abstract: A system for controlling pressure applied in a well intervention operation using a physics-based model is provided. The system can include a stripper element that includes a pressure retention element for sealing a wellbore during an intervention operation that uses coiled tubing; a stripper circuit that includes a hydraulic actuator to apply a pressure to the pressure retention element; a processing device coupled to the hydraulic actuator that can receive, from the stripper circuit, a feedback signal. The processing device may receive a physical characteristic of a component and then determine, using data from the feedback signal and the physical characteristic, a minimum pressure level to contain wellhead pressure. The processing device may then output a command to cause the hydraulic actuator to change the pressure on the pressure retention element to be the minimum pressure level or within a pre-set deviation of the minimum pressure level.

Abstract: A downhole chemical reactor can be placed in a downhole environment to generate gas in-situ. This gas can pressurize an inner pressure chamber of the downhole chemical reactor to create a pressure-on-demand source or to maintain a constant pressure reservoir, depending on the configuration of a reactor controller coupled to an inlet of the inner pressure chamber. The inner pressure chamber contains one or more desired chemical reactants and the reactor controller operates to permit well fluid to flow from the wellbore and into the inner pressure chamber. The well fluid reacts with the desired chemical reactants and generates one or more gases such as hydrogen or carbon dioxide. The generated gases pressurize the inner pressure chamber and a pressure regulator coupled to the inner pressure chamber maintains a maximum pressurization of the inner pressure chamber. For a constant pressure reservoir, the reactor controller repeats this cycle indefinitely.
