Abstract: 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.

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.
