Systems and methods for performing an intervention operation in a wellbore using a friction reducer fluid include a coiled tubing insertable into the wellbore, a pump operable to pump the friction reducer fluid through the coiled tubing and into the wellbore, and sensors operable to detect wellbore conditions. A controller including a processor is operable to automatically predict a wellbore depth at which the coiled tubing will incur a lock-up in the future based on the wellbore conditions and control the pump to pump the friction reducer fluid though the coiled tubing and into the wellbore to prevent the future lock-up.

Systems and methods for optimization of wellbore operations of producing wells

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.
