It splits into two categories:
| Pressure Self-Pulse Test (SPT) | Pressure Pulse Interference Test (PIT) |
|---|---|
The pressure response to rate variation are both recorded in the same well | The pressure response to rate variation is recorded in the offset wells |
Workflow
...
| 1 | Designing flowrate variation pulse sequence for disturbing wells (also called generators) based on the field primary data |
| 2 | Field operations on suspending the downhole gauges (if PDG is not available) |
| 3 | Performing flowrate variations according to the PCT design |
| 4 | Retrieving the downhole gauges |
| 5 | Downloading the data from the downhole and surface gauges |
| 6 | Primary data processing (gauge syncronization and filtering) |
| 7 | Implementing pressure pulse-code decomposition (PCD) |
| 8 | Recognising the PTA type-library diffusion models for decomposed DTR/CTR and type-curve fitting them with analytical and/or numerical pressure diffusion models |
