Abstract: 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.

Abstract: Systems and methods for performing a wellbore cleanout operation in a production tubing in a wellbore extending through a reservoir. The systems and methods include a sensor usable to detect a wellbore production volume of a production fluid from the production tubing per unit time, a conveyance, and a controller including a processor. The controller is operable to automatically determine a differential flowrate for locations along the production tubing based on a difference between a recorded flowrate and a modeled flowrate at the locations, determine any of the locations where the differential flowrate is equal to or greater than a predetermined threshold, and control deployment of the conveyance into the wellbore to perform the cleanout operation at any of the determined locations where a change in a wellbore cleanout utility function using the modeled flowrate compared to using the recorded flowrate is equal to or greater than an improvement factor.

Abstract: Systems and methods for performing a gas lift operation using gas to increase production of production fluid through a production tubing in a wellbore. Included is an optical bubble sensor usable to detect bubbles per unit volume of the production fluid in the production tubing. Also included is a pump operable to pump gas into an annulus in the wellbore outside the production tubing, a valve operable to control whether gas from the pump enters the annulus, and a controller comprising a processor. The controller is operable to automatically convert the detected bubbles per unit volume into a gas/liquid saturation index (GLSI) using a transformation function; automatically execute, at designated intervals, a decision function based on the GLSI to either pump or not pump gas into the wellbore; and automatically control the pump and the valve to pump gas into the annulus when indicated by the decision function.

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.
