Webb18 jan. 2024 · The total porosity (PHIT) varies in the range 0.03–0.08 and the effective porosity (PIGE) varies in the range 0.01–0.06, both from NMR logging. When paramagnetic minerals are not present in the matrix, NMR logging is very useful for measuring porosity independently from the composition of the matrix.
