Water well in limestone enhance production?

Post by sayraleticia »

Hello everyone

I did geophysics and ran electric log to a well which seems to be very good but the flow test was about 8 liter per second.
I consider the well to be plugged.

Any suggestions on my log interpretation ?
How can I unplugged the well assuming my log interpretation is correct.

Log shows
Caliper
Gamma Ray
Resistivity 8, 16, 32 and 64"
Resistance
SP.


Thanks

I have done some geophysical borehole loggings before, but I am curious how you define plugging the water well. I guess if you plug the well only at the bottom, then you can still do the logging?

My concerned is that the log shows a good producing zone from 110 to 290 meters but the well only produced 8 liters per second. I was expecting at least 40 to 50 lps.

Unless I am doing a wrong interpretation in the log. I am open for any comments either on the log if my interpretation is correct or not

Also if my interpretation is correct, how should I stimulate the well with mechanic proxedure or with acid to remove the mudcake. Any advise?

Thanks

I guess high resistivity zones correspond to fresh water bearing zones? And interestingly these zones have relative "flat" caliper readings. Maybe these zones are plugged?
