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.

Downhole tools and methods of controlling downhole tools

A tension measurement assembly, for measuring and monitoring a tension force in a cable being deployed from a spooling device on which the cable is spooled, comprises at least one force sensor disposed adjacent the spooling device for sensing a force applied to the spooling device and generating a force signal representing the sensed force, and a processor responsive to the force signal for calculating and monitoring a tension force present in the cable. A cable sensor engages the deployed cable for sensing a spooling/unspooling rate and a length of the cable moving past the cable sensor in a pre-determined time period and generating a spooling signal representing the sensed rate and length to the processor for use in the calculating and monitoring of the tension force.

Assembly, system and method for cable tension measurement

A method for controlling the tension in a spooled device disposed on a winch, comprises providing an input signal to a controller indicative of a measured tension in the spooled device, providing an input signal to the controller indicative of a desired tension in the spooled device, and providing an output signal from the controller to adjust the speed of the winch based on a difference between the desired tension in the spooled device and the measured tension in the spooled device.
