Ann: Multiple Farm-in Bids Received & Wellpad Construction Start, page-63

Hello all,
Appreciate to analysis. New here and not yet invested but thinking about it. By no means I am trying to down ramp but rather to understand the risk with IVZ.
Would you, or anyone here know much about the actual technicalities and especially Oil-Water Contact/Gas-Water Contact (OWC/GWC)?

Apparently this is the biggest pre drill uncertainty and can easily cut resource estimates quite a bit, up to 80%? I do not know much about this subject so I wondered if anyone here would know anything more about?I have tried going through the independent study by Getech and past presentations with no mention of this.
I only came about this information through Equivest Twitter post and got me thinking:
