TELEMETRY ON TUBING

摘要

In some embodiments, an apparatus and a system, as well as a method and an article, may operate to program a first acoustic repeater to transmit information at a first operating frequency; to couple the first acoustic repeater circumferentially around a coiled tubing portion, an inner diameter of the first acoustic repeater being about equal to an outer diameter of the coiled tubing portion; to program a second acoustic repeater to receive information transmitted by the first acoustic repeater; and to receive sensor information transmitted at the first operating frequency by the first acoustic repeater and relayed by the second acoustic repeater, the second acoustic repeater being coupled to the coiled tubing portion uphole from the first acoustic repeater. Additional apparatus, systems, and methods are disclosed.
