Abstract
A zonal isolation assessment system includes a receiver, production tubing disposed in a wellbore, a zonal isolation assembly, and an assessment assembly. The zonal isolation assembly is fluidically coupled to the production tubing. The zonal isolation assembly includes isolation tubing that flows production fluid from the wellbore to the production tubing, a first sealing element, and a second sealing element to fluidically isolate an internal volume of the isolation tubing from an isolated annulus defined between the isolation tubing and the wall of the wellbore. The assessment assembly includes a first pressure sensor at the internal volume of the isolation tubing configured to sense a first pressure value and a second pressure sensor at the annulus and configured to sense a second pressure value. The assessment assembly transmits to the receiver the first pressure value and the second pressure value to determine the integrity of the zonal isolation assembly.
