The flow rates need to be considered in context to the specified aims of the fracture stimulation. Refer to pg 29 of this earlier presentation, in which PANR lay out the aims of the different stimulations in advance, so investors expectations of what success looked like were understood . Mostly they were data gathering, with the objective of gathering samples and proving the oil is mobile.
Only the SMDB had a pre test guide at 50-80bopd being considered a success, note they had a blockage in this case, so no cigar at that time

I will caution that there are a number of variables that need to be understood, before declaring a success number
How large is the frack, the amount of water and sand/proppant used
How effective is the frack, what percentage of design has been achieved
How aggressively has it been flowed, in both the top of well choke setting and pressure drop at the bottom of the well
Think of aggressively as the scenario of a garden hose, flow is set by how open the tap on the wall is, and how open the nozzle on the end of the hose is, either end will determine the flow
The wall tap is how effective and large the fracture is, this gives contact with the reservoir
The nozzle is the choke orifice at the well head
A third factor is the weight of the fluid column in the well, it sets the pressure at the bottom of the well in flowing condition. Nitrogen is going to be injected part of the way down the well, to displace fluids with the much lighter gas, so reducing the pressure at the bottom
This sets the differential pressure between the well bottom and the reservoir itself, hence its flow rate
