Patent attributes
A status of an isolation barrier can be determined by comparing data collected by a sensor below the isolation barrier to data collected by a sensor above the isolation barrier. A sensor assembly can be coupled to an isolation barrier assembly downhole from the isolation barrier assembly for collecting data related to a characteristic of the wellbore. The sensor assembly can transmit the data collected to a tool positioned up-hole from the isolation barrier. The tool can transmit the data to a surface of the wellbore. The sensor assembly can be powered by a battery pack or via a connection to a downhole tool that supplies the power to the sensor assembly. The downhole tool that receives the data from the sensor assembly (and optionally provides power to the sensor assembly) can be inserted and removed from the wellbore over the lifetime of the well.
