Nuclear Magnetic Resonance for Materials Characterization

Green Imaging is a global leader in nuclear magnetic resonance based porous media analysis and as such will present an overview of our methods for fluid characterization in porous media. The focus will be on “traditional” hydrogen detection as well as new research on carbon 13 and sodium detection. NMR can be used to provide a long list of measurements including porosity, permeability, capillary pressure, relative permeability, and wettability. All NMR measurement techniques are non-destructive and as such many experiments are comparative, allowing users to look at changes in the sample over time, or with varying conditions. Using NMR to characterize the fluids in the porous media allows users to characterize the media itself and come to a better understanding of full character of the media of interest. NMR highlights the interactions of fluids with the porous media and understanding this interaction is key to many users’ interests.
