water production issue in dry gas reservoir

[Smriti]

Plz explain how to do this rate transient analysis....yes this is an Indian field..

Two more things to check in addition to the above good points

1. You don't mention what WGR's you are talking about, and whether or not salinities are increasing - could it simply be condensation increasing? As a gas reservoir depletes, its ability to hold water vapour increases - so it equlibrates with connate water which shows up as increasing WGR's late life. On a side note, have you plotted your water salinities over time and compared to known reservoir (and if you have it) over/underlying water salinities?

2. Could it be channeling behind casing? Poor cement jobs can exhibit worse characteristics as depletion occurs

Vinomarky is right. People so easily tend to forget that our work is not rocket science.....and that our work is only as good as the reservoir monitoring we do. Yes, salinity is an option. Maybe Chan plots to get a crude idea of source of water. Check CBL/VDL for integrity behind pipe. So many options, Smriti......its about solving problems in the field with the tools at hand. Go for it and let us know how you fare.

yes i checked the salinity ...salinity is for the total field and not well wise...and with time salinity is showing increasing trend...
