RE:Class is in session Lol..this is my hobby.. The sediments in proximal fan such as Kawa should not be an issue ..coarser than the floor fans yes but porosity and permeability still very good ..am not quite getting the channel and how this best fits the migration ..does it help the migration does it hinder ..does it really provide a lateral seal or does it block create a wall? Oyler ..what are your thoughts? What's the Word? https://vm.tiktok.com/ZM8GQkp7T/
