I am also reaching a bit on the permeability, but go on the basis that it is analogous with Haynesville (stated by 88e https://www.asx.com.au/asxpdf/20160317/pdf/435xckp7dzrp7t.pdf) which has an effective cut off of 100 nanodarcies and average of less than 1000 nanodarcies https://academic.oup.com/gji/article/195/1/315/608267
That places it at< 0.001 md on the picture below, which seems to fit in the middle of the shale band


The N2 to gas transition is not in any company release, more a can than will statement from me, but was the normal process used where I worked offshore when a nitrogen start was required. Our field required continuous gas lift using produced gas which would deplete on complete depressurizations ( plant and well to subsea valves) N2 generation was then used to rebuild the gas lift volume, until kickoff is achieved. I would not expect the HRZ to need continuous gas lift, just long enough to get the frack fluid out of the way.
