📍SKIN EFFECT- The vicinity of the wellbore has characteristics that are different from those in the reservoir as result of drilling and well treatment operations.
The skin effect reflects the difference in pressure drop that exists in the vicinity of the well
The reservoir as it is, and as it would be if its characteristics (especially permeability) were uniform right up to the wellbore.
Well treatments are performed by acidizing to improve the near well permeability and thereby reduce the skin value.
In Hurst and Van Everdingen’s approach, the pressure drop due to the skin effect is located in an infinitely thin film around the wellbore
