Permeability Estimation with Nuclear Magnetic Resonance (NMR) Logs
Permeability estimation from NMR logs uses the fact of the pore-water relaxation time being inversely related to the surface area-volume (S/V) ratio of the pore space. The NMR estimate of permeability is based on theoretical and core-based models that show that permeability increases with increasing porosity and pore size.
