Claim 18:
19. A method for running an untethered downhole tool in a wellbore, comprising:
inserting the untethered downhole tool into the wellbore at a terranean surface, the untethered downhole tool comprising a body, one or more sensors positioned in the body, and at least one orientation component positioned in, or attached to, the body;
running the untethered downhole tool within the wellbore in a direction downhole of the terranean surface and toward a subterranean formation independent of a downhole conveyance attached to the body;
adjusting, with the at least one orientation component positioned in, or attached to, the body, an orientation of the body in response to one or more forces acting on the body as the downhole tool runs in the wellbore in the direction downhole of the terranean surface, the adjusting comprising:
adjusting the orientation of the body relative to the one or more forces acting on the body with a first of the at least one orientation component comprising a buoyant portion that generates a buoyant force of the one or more forces acting on the body in an uphole direction, the buoyant portion positioned within, or attached to, a first location of the body at or near an uphole end of the body;
adjusting the orientation of the body relative to the one or more forces acting on the body with a second of the at least one orientation component comprising a ballast portion that is positioned within, or attached to, a second location of the body at or near a downhole end of the body;
adjusting the orientation of the body relative to the one or more forces acting on the body with a third of the at least one orientation component comprising at least one magnet that is positioned within, or attached to, a third location of the body; and
adjusting the orientation of the body relative to the one or more forces acting on the body with a microcontroller, wherein adjusting the orientation of the body with the microcontroller comprises:
detecting an immobilization of the downhole tool based on outputs of the one or more sensors, and
reducing, in response to the detection of the immobilization, a magnetization of the at least one magnet to reduce a pull force towards a casing.
