Nuclear magnetic resonance (NMR) spectroscopy has become an increasingly important technique in recent years for the characterization of porous materials. In particular, its importance in petroleum exploration has been enhanced by new NMR well‐logging techniques for the characterization of both rocks and natural fluids. Such advanced techniques have been accepted as one of the most valuable logging services. There are several areas currently being developed in the study of pore structure and rock heterogeneity including the physics of internal magnetic fields, the two‐dimensional NMR paradigm, heterogeneity decomposition, and the mathematics of Laplace inversion. Although the methods have been developed for rocks, they are generally applicable to partially saturated porous media such as the vadose zone.
