Apparent Water Resistivity (Rwa) - Archie

Where:
• Rwa= apparent resistivity of formation water
• Rt= true formation resistivity as derived from a deep reading resistivity log
• ɸ = porosity
• a= tortuosity factor
• m= cementation exponent

Calculate Apparent Water Resistivity (Rwa)
Rt (ohm-m)		ɸ (dec)
m		a

Results

Apparent Water Resistivity (Rwa) - Results
Rt (ohm-m)	ɸ (dec)	m	a	Rwa (ohm-m)
