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.

Downhole barrier and isolation monitoring system

A downhole barrier device comprising a housing having a design and a rupture layer formed with the housing and having another design. The housing and rupture layer are integrally formed using a laser melting process and have a density greater than 98 percent. The laser melting process is performed using a 3D printing process. The other design can be selected from a plurality of designs including at least two of: at least one fabricated stress concentration; at least one pattern of thickness less that of a thickness of the design; a sealing layer, a support layer, and a flow hole; and at least one shape selectable selected from a disc shape, a pinched shape, a folded shape, and a curved shape. The downhole barrier device can be formed using a metal selected from a plurality of metals and be selected based on operational use of the downhole barrier device.

A diagnostic coating is applied to the surface of a wellbore service tool. The diagnostic coating has one or more constituents that undergoes an optically-detectable physical change responsive to changing values of one or more downhole parameters. After exposing the diagnostic coating of the service tool to the downhole environment, the tool may be retrieved from the wellbore and inspected to detect any physical change indicative of the service tool having been exposed to elevated values of the one or more downhole parameters.
