The CMR-Plus* Combinable Magnetic Resonance tool with high-logging-speed capability makes nuclear magnetic resonance (NMR) measurements of the buildup and decay of the polarization of hydrogen nuclei (protons) in the liquids contained in the pore space of rock formations. One primary measurement of the CMR- Plus tool is the total formation porosity. Borehole NMR measurement is unaffected by solid materials, so the measurement is not sensitive to matrix type and therefore lithology independent.
