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.

Milling and catching devices

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.

Annular cutter catching devices

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.

System and method for mechanical tubing puncher

A downhole tool that has a plurality of arm assemblies. Each of the arm assemblies has an arm configured to expand and retract and an actuator. A hydraulic bus in fluid communication with the plurality of arm assemblies. A plurality of flow control devices. The flow control devices are configured to selectively isolate one or more arm assemblies of the plurality of arm assemblies from the hydraulic bus while maintaining the other arm assemblies of the plurality of arm assemblies in communication with the hydraulic bus.
