Systems and methods of the present disclosure relate to identifying geometric features of a conduit. A method includes controlling a flow into or out of a conduit to induce pressure waves in the conduit; measuring, with a pressure transducer, pressure responses in the conduit due to contact of the pressure waves with a geometric feature of the conduit; and identifying the geometric feature, based on the pressure responses.

Feature determination and calibration of pipeline geometry and features utilizing controlled fluid waves

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 pigging tool may include a housing positionable in a pipeline. The housing may define a bypass channel that extends along an axis that is nonparallel to a longitudinal axis of the housing. An energy generation device can be positioned in the bypass channel of the housing such that fluid is receivable by the energy generation device to generate energy for the pigging tool. Further, an energy storage device may store energy generated from the energy generation device. The energy storage device may provide the pigging tool with energy to perform one or more operations in the pipeline.

Energy generation device for a pigging tool in a pipeline

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.

Controlling surface pressure during well intervention

A system is provided including a coiled tubing reel apparatus including a reel drum for storing a coiled tubing string spooled on the reel drum and a hydraulic reel drive motor that controls rotation of the reel drum. The system further includes a reel controller that determines an estimated reel back tension for a portion of the coiled tubing string between the reel apparatus and the injector based on a set of parameters related to a coiled tubing operation. The reel controller determines a target reel back tension to be applied to the portion of the coiled tubing string by adjusting the estimated reel back tension based on a historical job dataset. The reel controller then determines and sets a target hydraulic pressure of the reel drive motor to achieve the target reel back tension in the portion of the coiled tubing string.

Reel control in a coiled tubing system

A system is provided including a coiled tubing injector including at least two gripper chains for gripping a coiled tubing and a gripper system for generating a gripper force applied to the at least two gripper chains by adjusting gripper pressure on at least one gripper cylinder. A gripper controller is configured to determine a minimum gripper pressure and a maximum gripper pressure for the gripper cylinders, based on a current set of parameters related to lowering the coiled tubing into a wellbore or pulling out the coiled tubing from the wellbore. The gripper controller selects a target gripper pressure between the minimum gripper pressure and the maximum gripper pressure based on a historical data model and sets the target gripper pressure for the at least one gripper cylinder.

Gripper control in a coiled tubing system

A system is provided that includes a dart, a pressure sensor, and a controller communicatively coupled with the sensor. The dart is disposed in a fluidic channel. The dart has a main body and a flange extending from the main body and has a diameter greater than or equal to a diameter of the fluidic channel. When the dart translates within the fluidic channel and passes a location of a variation in the fluidic channel, the flange creates a pressure pulse. The pressure sensor measures the pressure pulse within the fluidic channel created by the dart. The controller determines the location of the variation based on the measured pressure pulse.
