Сased-hole logging technique assessing the borehole flow profile (PLT-BFP) and reservoir flow profile (PLT-RFP).
The survey is performed with a multi-sensor donwhole PLT Logging Tool and interpreted with PLT-BFP Model or PLT-RFP Model.
ILT is essential part of the production and recovery monitoring and helps understand fluid communication at wellbore ↔ reservoir contact.
Objectives
Picking up the fluid injection intervals |
| Estimating injection rate across each injection interval |
| Check up for cross-flows in shut-in conditions between formation units with different formation pressure |
Picking up the zones of the first barrier (tubing and/or casing) integrity failure |
| Injection is going to the upper and lower part of perforation with majority of water going to the upper part and the most of perforations are not taking water. |
