Abstract
A006 INTERPRETATION ENHANCEMENT BY COMBINING SIP AND NMR Introduction 1 The nuclear magnetic resonance (NMR) technique is mainly known in geophysics for well logging and laboratory measurements of cores. Therefore most publications in geophysics deal with the NMR properties of hard rocks. NMR is observed with nuclei of certain atoms which are immersed in a static magnetic field and exposed to a secondary oscillating magnetic field. The advantage of NMR is based on its direct sensitivity to hydrogen (water) protons ( 1 H). Furthermore structural parameters as porosity pore size distribution or permeability of porous media can be determined by
