In this case the Arps analysis is not useful since there is no significant rate decline during the
history. The Fetkovich plot is not useful either since its validity assumes constant flowing
pressure which is not the case in this example.
This highlight the necessity to model the well production behavior with theoretical models
taking into account reservoir geometry and material balance, similar to those used in pressure
transient analysis, as these are the only tools that can make reasonable forecast in such cases.
