>okay - what are Vizado and Vizfogo?

Vizado is water. I don't know what Vizfogo is. The presentation is about geothermal resources in Hungary, but permeability means the same thing, whether you are looking for gas, oil, or water. The numbers they show seem way too high though, I can't imagine the permeability being that high. In fact in Ben Laws presentation that he's doing in June, he states "Reservoirs typically are sandstone with low-permeability (<0.1md) and porosity (< 14%)"
