Skin localization at wells drilled in a vertical fault zone.
The efficiency of wells drilled into fractured zones that act as draining conduits in hard rock aquifers can be strongly reduced by skin effects. In such aquifers, skin effects (well losses) can appear in close proximity to the well and/or at the contact between fracture and formation. In this paper it is shown how to locate those skin conditions in the case of two wells that have been drilled in a single vertical fault with infinite conductivity.
