INPUTS	Assumptions: - Short normal curve reads in the invaded zone - Long normal curve reads beyond it.
	Depth =
	Long normal curve resitivity =
	Short normal curve resistivity =
	Formation water resistivity, Rw =
	Define optional porosity model:	a = m =
RESULTS	Water saturation, Sw =
	Porosity% from Archie model (limestone: a=1, m=2) =
	Porosity% from Humble model (sandstone: a=.62, m=2.15) =
	Porosity% from optional model =
