Advanced coatings for downhole applications

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...

Beschreibung
Zusammenfassung:	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.
