The most popular practical range of skin-factor variation is 

LaTeX Math Inline
body-5 < S_M < 8
 with upper limit going arbitrarily high.

For the negative skin-factor values there is a natural limitation from below caused by the Mechanical Skin concept itself.

The Mechanical Skin concept is trying to approximate the true inhomogeneity of the near and far reservoir zones with homogenous far reservoir model and additional pressure drop at the well wall.

In case of high permeability

The values of

bodyS_M < -5
 are usually not supported by the majority of commercial simulators as these values assume almost infinite permeability in the 10 m area around the well seesee
