Abstract: A technique that is usable with a well includes deploying a plurality of location markers in a passageway of the well and deploying an untethered object in the passageway such that the object travels downhole via the passageway. The technique includes using the untethered object to sense proximity of at least some of the location markers as the object travels downhole, and based on the sensing, selectively expand its size to cause the object to become lodged in the passageway near a predetermined location.

Abstract translation: 可用于井的技术包括将多个位置标记部署在井的通道中并在通道中展开无束缚物体，使得物体经由通道向下行进。 该技术包括当物体在井下行进时使用未受扰的物体感测位置标记中的至少一些的接近度，并且基于感测，选择性地扩大其尺寸以使物体被容纳在靠近预定位置的通道中。
