A borehole fishing tool, including a grapple for fixedly attaching to a fish in a borehole, a tool housing to which the grapple is connected, and at least one camera, mounted in the tool housing, to generate at least one image of the fish in the borehole. The borehole fishing tool also includes at least one light source, mounted in the tool housing, to illuminating a portion of the borehole between the at least one camera and the fish, a connector attached to the tool housing to connect the tool housing to a conveyor, and a telemetry transceiver to transmit at least one image of the fish through a telemetry channel in the conveyor to a computer system at an Earth's surface.

A ferromagnetic disk is removably installed in a wellbore. The disk can be installed in the wellbore during oil and gas well completion and production activities to maintain pressure within the wellbore and then can be dislodged. More specifically, a strong magnet is installed within a magnetic tool to dislodge and remove a ferromagnetic disk without breaking the disk. The strong magnet can be a neodymium magnet, electromagnet, or other types of strong magnets.

Systems and methods for retaining magnetic debris from drilling fluid include an exterior sleeve with an interior space receiving an interior holder. A first end of the exterior sleeve is connectible to drill string to place the interior space in fluid communication with the drill string, and a longitudinal passage between the interior holder and exterior sleeve defines a flow path for drilling fluid from the drill string. Magnetic materials along and/or around the interior holder provide a magnetic field extending into or across the longitudinal passage such that magnetic debris is removable by the magnetic field from the flow path of drilling fluid passing through the longitudinal passage.

A debris collection tool includes a mandrel having a longitudinal flowbore therethrough and an inner sleeve disposed around the mandrel. A first array of magnets is arranged on the inner sleeve. A second array of magnets is disposed around the inner sleeve. The first array of magnets is moveable with respect to the second array of magnets. The debris collection tool further includes an adaptor sleeve concentric with the mandrel and a linkage coupling the adaptor sleeve with the inner sleeve.
