Resistivity derived porosity (Sw= 1)
Resistivity derived porosity (Sw= 1)
- Where:
- ɸ= porosity
- 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
