Abstract: Systems and methods are disclosed herein for performing a milling operation within a wellbore in an oil-and-gas setting. An example system can include a milling tool, which can include a cutting head, a linear actuator configured to advance the cutting head, and a linear displacement measurement sensor associated with the linear actuator. The sensor can be configured to measure linear displacement of the linear actuator. The system can also include a cable to lower the milling tool, a control unit that receives data from the sensor, and a display device that displays a visualization of the data from the sensor. The control unit can analyze the data to determine a location of a milling target, a status of the milling operation, and undesirable milling conditions down hole. The control unit can perform a remedial action, such as by turning on a pump to remove debris from the wellbore.

Abstract: A milling system may be used to remove the portions of a failed valve that is blocking the wellbore. When milling a partially open valve obstructing the wellbore, the target material to be removed may not be present at the central axis of the wellbore causing the target material to not fully surround the milling bit, which may cause the bit to be deflected away from the target during milling reducing milling efficiency. The disclosed milling system may be used to mill out and capture the coupon for any downhole obstruction that does not have any material near the center axis of the wellbore. A first embodiment of the milling system may be configured to fully mill out material within the wellbore while a second embodiment may be used to mill out material within the wellbore and further catch the milled material or coupon.

Abstract: An annular cutter catching device includes a housing having an inner bore therethrough, a cutter configured to cut a coupon, and a coupon catching device configured to grip an outer surface of the coupon. In an embodiment, an annular cutter catching device includes one or more split rings disposed within the inner bore of the housing. In the embodiment, at least one split ring is configured to grip an outer surface of the coupon within the inner bore of the housing. In an embodiment, an annular cutter catching device includes a coupon catcher disposed within the inner bore of the housing. In an embodiment, the coupon catcher includes a set of fingers movable between an open position and a closed position. In an embodiment, the set of fingers are configured to retain the coupon within the inner bore of the housing in the closed position.

Abstract: A downhole puncher tool may include a pump system configured to produce a force. The downhole puncher tool may include a plurality of arm systems. Each arm system may have one or more arms that are configured to extend radially outward from the downhole puncher tool upon receiving the force from the pump system. In some embodiments, at least one arm system of the plurality of arm systems comprises a punching insert that is coupled to an arm of the one or more arms, and the punching insert may have a projecting surface.

Abstract: An apparatus for remote actuation of a downhole device in a wellbore, that includes a cable head configured to connect with a cable in communication with surface equipment. The cable head is connected with a tractor module. A communication module is connected with the tractor, and a release device is connected with the communication module. The release device is connected with an anchor. The anchor section is connected with a downhole device. The downhole device is configured to communication with the communication module when the communication module is released from the release device.
