A set of Well & Reservoir Surveillance operations with a particular purpose to reveal and locate unintentional fluid leakage through well completion.
Below is the list of popular methods of Leak Detection:
| Surface Leak Tests | Downhole Leak Logging | ||||
|---|---|---|---|---|---|
| Bleed-off Test | Annulus Pressure Test | Leak Tracer Test | Leak PLT Logging | Leak Temperature Logging | Leak Noise Logging |
The primary concern on the fluid leakage is the presence of Sustainable Annulus Pressure (SAP) but not all the leaks expose themselves through SAPs, like for example the casing leak below the tubing packer.
