Water Saturation - Archie Method
INPUTS	Depth =	MODELS: Archie: (limestone) a=1, m=2, n=2 Humble: (sandstone) a=0.62, m=2.15, n=2 Mod. Humble: (sandstone) a=0.82, m=2, n=2
	a =	m =
	n =	Porosity% =
	Rw =	Rt =
SHALE CORR	No correction Correct for shale
	Old rocks Tertiary rocks
	Gamma-ray, clean =	Gamma-ray, shale =
	Gamma-ray of zone =	Shale resistivity =
RESULTS	Gamma-ray index =	Volume% of shale =
	Water Saturation% =	Formation Factor =
	Apparent Water Resistivity, Rwa =
	Is Rwa > (3*Rw)?	Rwa>3*Rw can indicate production
	Bulk Volume Water%, BVW% =	For water-free production, BVW<7% for SS, BVW<4% for LS

When you finish your calculations,
select the recorded data, copy it,
and then paste it into a spreadsheet
as comma-delimited values to save it.
