p_{wf}(t) = p^o_{wf}(t)| - \frac{q_t}{2 \pi \sigma} \ S_M |
with the meaning that near-reservoir damage is resulting in additional pressure drop quantified by the value of mechanical skin
It quantitatively characterises permeability change in a thin layer (usually < 1 m) around the well or around the fracture plane, caused by stimulation or deterioration during the reservoir invasion under drilling or well intervention or under routine production or injection.
