Abstract
Cement plug parameters in a wellbore may be monitored by providing a cable through the cement plug before the cement plug sets. The cable comprises one or more sensors that monitor the parameters, and the sensors are operated to transmit measurement data to the surface. The parameters may include temperature, pressure, conductivity, vibration, acceleration and impedance.
