Resistivity derived porosity

Home Equations Español

Resistivity derived porosity (resistivity porosity)

Where:
• ɸ= porosity
• Sw= water saturation of the uninvaded zone
• Rw= resistivity of formation water at formation temperature
• Rt= true formation resistivity (i.e., deep induction or deep laterolog corrected for invasion)
• a= tortuosity factor
• m= cementation exponent
• n= saturation exponent

Calculate Porosity (ɸ)
a		Rw (ohm-m)
Rt (ohm-m)		Sw (dec)
n		m
