NMR Relaxation in Porous Media for Environmental Applications

Nuclear magnetic resonance relaxation is a powerful, non-intrusive technique, which has been extensively used in several areas of science and engineering to study the behaviour of fluids in porous media, as well as the structure of the porous media themselves. In this chapter, we introduce the very basics of the theory behind these methods, and we explore some of the ways in which they have been used to study the properties of soils and porous rocks, for several different topics relevant to current environmental issues.
