Squariel - as far as I understand, the fractured basement play here is based on migratory helium transported some distance to the well location, in deep geothermal fluid, which is then liberated in hole as rising gas to surface. Water isn’t a problem, and the geothermal carrier is a bringing a near endless supply of gas (it’s not a static reservoir), the issue is flow rate. Higher up, the Karoo layer is then more like a classic trap and seal system for that rising gas, so that’s more like doing a traditional O&G reservoir estimate model, I think. The technical challenge appears to be how to develop a complex model accommodating both a novel dynamic gas generation system and static reservoir estimates in a way that meets existing O&G industry standards for proven resource estimation.
