Abstract
A system for communicating information, particular for use in a hydrocarbon well, is described including one or more releasable vessels having radio frequency (RF) circuitry responsive, when in use, to an RF reader system, the vessel including counteracting means to reduce the effect of destabilizing flow forces thereby extending the coupling time with the reader system.
