Abstract: A seismic generation system may include an electrical source, a conductor coupled to the electrical source and to be positioned in a wellbore in a subterranean formation with a casing therein, and a seismic generation source assembly to be positioned in the wellbore and coupled to the conductor. The seismic generation source assembly may include a source element having a sealed housing, an armature within the sealed housing, source electromagnets coupled to the armature, and electromagnetic clamps coupled to the armature, each electromagnetic clamp having opposite magnetic poles. The sealed housing may include respective ferromagnetic portions adjacent the opposite magnetic poles of each electromagnetic clamp, and non-ferromagnetic portions between the opposite magnetic poles of each electromagnetic clamp.

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.
