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: 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.
