"The Operator plans to run a production logging tool (PLT) over the reservoir section on Tuesday June 2 to evaluate the gas rates from each of the 7 fracture stimulation zones and to identify the source of the fluid in the wellbore. It is
possible that the well is tapping a small aquifer. If so, the production logging will identify the location of this water source and help determine how this zone could be sealed off."

I guess, they would have loved to avoid to frac into an aquifer. Do you know what type of methods there are to seal off the water source?
