If it is not completed across the watered out section, then you could expect very good oil production, until the water reaches the perforations. From your description, reservoir 2 is above reservoir 1. It would be useful to have a description of the well completion depths (casing shoe and where perforated and where log shows oil water contact). If the whole of reservoir 2 is perofrated, then the cnditions under which the log was run is important (well flowing/shut in, etc.) and what type of log was it.
The log that was performed is TDT.
and yes it makes sense now coz all the upper part was perforated with a very small part of the lower section ..
but how can the high saturation act as a water drive ? we're not sure if it's active or no ! how can i prove it ?

reservoir 2 is producing more water that reservoir 1 as well .. this is due to the perforation as i said earlier ..

and i can say that usually the cased hole has a better flow than the open hole ? so reservoir 2 has more production !

but now help me to prove the water drive thing !


thank you very much i really appreciate it !
