Abstract
An apparatus and method may operate to mount one or more communication assemblies relative to the exterior of a casing being placed in a borehole. Two communication assemblies can be placed in longitudinally spaced relation to one another along the casing, wherein each communication assembly is configured to obtain data from RFID tags in one or more azimuthally oriented regions of the annulus surrounding the casing, and to interrogate RFID tags in a first fluid in the borehole. Additional apparatus, systems, and methods are disclosed.
