d) All of the above.
Scenario:
A wellbore has experienced a sudden pressure drop in the inner annulus during a CMIT – TxIAxOA test. The tubing and outer annulus pressure readings remain stable.
Task:
**Possible Cause:** A leak in the inner annulus, possibly caused by a crack in the production casing, a failed packer, or a corroded connection.
**Potential Risks:** * Loss of injection fluid, reducing well efficiency. * Contamination of the production stream with injected fluid. * Environmental hazards due to potential release of injected fluid into the surrounding environment. * Possible failure of the inner annulus leading to a collapse or a connection failure.
**Possible Actions:** * Isolating the affected section of the well. * Performing a thorough inspection to identify the location and cause of the leak. * Repairing or replacing the damaged component. * Re-testing the inner annulus to ensure the issue has been resolved.
