What is the difference between the FWL package and the WEL package? If you are using the FWL4 / FWL5 package, can you also use the standard WEL package?
The FWL4/FWL5 package should be used instead of the WEL package, even for wells that lie within a single cell, specially for extraction, because the FWL package checks for unphysical drawdowns, and reduces the pumping accordingly, to maintain bottom-hole conditions. Both may be used in a simulation, but the WEL package should be used only in locations where the well is not expected to go dry since this package does not check for unphysical conditions.
