Do we need West Erregulla 2 to reach 90 mmscf/d

    Just to amuse myself, I've been going through the old 2017 AWE announcements on Waitsia 4 (W4) to try and get a better comparison to our West Erregulla (WE1)
    First thing I was looking for was the final casing diameter at W4 to allow an instantaneous gas flow of 90 mmscf/d and exactly where it came from. The diameter of the casing through the Kinga sandstone is 9 5/8 inches at W4. Pretty big compared to our WE1 of the 5 1/2 inches of production casing we are running. As some will know, gas flow and pressure varies significantly over distance and casing diameter however I'm not techy enough to calculate maximum flow rate differences between 3,379 meters through 9 5/8 inch tube compared to 4,761 meters through 5 1/2 inch tube. (Maybe someone could help here)

    What i also found is that W4's 90 mmscf/d of gas came from the Kinga sandstone only. Although the High Cliff showed elevated gas readings at W4, analysis showed this to be a tight reservoir and didn't flow gas. Our WE1 High Cliff has a gross of 22 meters gas saturated zone with a 10 meter zone of 10-16% porosity that should flow gas, this is a bonus pay compared to W4. (I'm going to put this bonus zone aside for this comparison though)

    Ok, my conundrum is, W4 has a gross gas column of 42 meters with a net pay of 21 meters in the Kinga. WE1 has a gross column of 97 meters with a net pay of 41 meters in our Kinga. Now assuming both wells have identical porosity, in theory WE1 "should" flow double the gas as W4. If this was the case what would we see at the surface? With the reduced tubing diameter and increased depth of 1,382 meters, would it even be possible to out-do the 90 mmscf/d flow rates through such a small tube.
    Hence the title of this thread, would we need to drill a WE2 straight to the Kinga Sandstone with less intermediate casings so we hit total depth with a decent size production hole. Would this scenario be required to out do the flow rate of W4 so STX can hold the crown of the largest on shore gas flow rate in Oz
    Who out there can calculate this before we flow test ?
