Cole Plot in MBAL
[glow=red]P/Z trend of my dry gas reservoir is showing strong water support i.e deviation from straight line. Cole plot on MBAL is also showing incrasing trend. But the production of the well does not show any water indication. On MBAL, I have tried to match different water models but not any one of them is matching i.e Cole plot does not become horizontal. Can anybody tell me what can I do in this case to estimate GIIP and Water enchroachment of this well?
Do you think your pressure measurements are correct?
also what is the production period? it is not necessary that you will start producing water at the begining.
Also did you consider any other pressure support from may be another fault block which is not fully sealing?
finally Do you mind sharing a little bit more detail?

The well has produced 25 BCF in 4 years. P data seems to be ok. Reservoir sand distribution in not very clear. Could it be the justification that some other gas tank is giving support in terms of pressure? Even after enough shut in time, the static bottomhole pressure was not stable. P/Z GIIP is quite high as compared to static. Usually the case should be reverse?
