Nuclear magnetic resonance (NMR) logs are a geophysical technique used to measure the properties of subsurface formations by detecting the magnetic resonance signals of hydrogen nuclei in fluids within the pores of rocks. This method provides valuable information about the porosity and fluid saturation of reservoir rocks, making it a crucial tool in understanding reservoir characteristics and groundwater studies.
