Сased-hole logging technique assessing the borehole flow profile (PLT-BFP) and reservoir flow profile (PLT-RFP) in producing wells.
The survey is performed with a multi-sensor donwhole PLT Logging Tool and interpreted with PLT-BFP Model or PLT-RFP Model.
PLT is essential part of the production and recovery monitoring and helps understand fluid communication at wellbore ↔ reservoir contact.
For PLT in injection well see ILT, although it is often called PLT anyway.
Objectives

...
Picking up the fluid inflow intervals and phase characterization |
| Estimating flowrate of each phase component across each inflow |
| 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 |
Oil Producer

| Fig.1 . PLT in producer with oil and water production. | Both perforations are producing oil and water with upper interval producing more than lower. The lower inflow zone is mostly producing water. |
Fig. 21 . PLT in water injector.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 oil producer with oil and water production. |
