is essential part of the production and recovery monitoring and helps understand fluid communication at wellbore ↔ reservoir contact.
Objectives
| Producer | Injector (water or gas) |
|---|---|
Picking up the fluid inflow intervals and phase characterization | Picking up the fluid injection intervals |
| Estimating flowrate of each phase component across each inflow interval | 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 | |
Deliverables
Oil Producer | Water Injector |

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. 2. 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. |
