Abstract
Radio frequency Micro-Electro-Mechanical System ('MEMS') tags are geometrically shaped using protective structures. The MEMS tags may be added to wellbore cement, and pumped downhole. In addition to protecting the MEMS tags from the harsh downhole environment, the protective structures produce a more rounded shape which, in turns, increases the flow efficiency of the MEMS tags. An interrogation tool may be deployed downhole to interrogate the MEMS tags, to thereby perform a variety of wellbore operations such as assessing the integrity of the cement seal.
