  • Patent number: 10563479
    Abstract: A bottom hole assembly (BHA) incorporates a tubular cutter driven by a downhole motor. A scraper moves into a smaller tubular to clean an area where a spear will later be engaged to the cut tubular portion. The scraper has a relatively movable mandrel that allows straight through flow into the motor or closes flow to build pressure to a telescoping jack to exert a pull force on the cut tubular after the cut is made. The spear is articulated with mandrel manipulation to grab the cut segment and weight is set down to shift the mandrel in the scraper to allow pressure buildup with rig pumps turned on to retract the jack as the BHA is held with anchors in the larger tubular. The cut segment is pulled uphole to loosen it so it can be removed from the borehole.

  • Publication number: 20190162048
    Abstract: The magnetic fishing tool has an axial flow passage through a valve member and one or more magnets for initial dispersal of debris away from the fish. Once engaged to the fish the flow direction can be altered by moving the valve member to open lateral ports and to close the straight through path so that fluid circulates above the fish to clear debris from ahead of the fish on the trip out of the hole. This can be accomplished with an object landed on a seat in the valve member, which causes it to shift axially to expose the lateral ports. Optionally the valve member can be shifted with flow in which case the flow will continue axially as well as laterally for the retrieval of the fish.
