Abstract: A method includes receiving a request to supply power of a first type to a toolstring. The toolstring includes a first tool that operates using the power of the first type and a second tool that operates using power of a second type. The method also includes receiving an indication of a relay configuration relating to relay positions of relays of a switching circuit in the toolstring. The relay configuration enables the switching circuit to selectively supply the power of the first type or the power of the second type to the toolstring via a switching communication system. The method further includes, when the relay configuration does not enable the switching circuit to supply the power of the first type, sending a first command to the switching communication system to change the relay configuration to enable the switching circuit to supply the power of the first type.

Abstract: Systems and methods for magnetically autonomously clamping a downhole component in a select direction of a borehole casing. The systems can include a sensor package that obtains a downhole measurement in a position in a cased borehole. The systems can include an integral magnetic clamp that removably clamps the downhole component (e.g., a downhole seismic shuttle) to the cased borehole. The systems can include a directional detector that outputs a select direction of the cased borehole relative to the downhole component. The systems can include a downhole controller that activates a portion of the integral magnetic clamp of the downhole component closest to the select direction output by the directional detector.
