Abstract: A method of measuring petrophysical information from a crushed porous media including performing one or more NMR measurements on the porous media fully submerged in an NMR visible fluid, performing one or more NMR measurements on the porous media alone following centrifugation, performing one or more NMR measurements on the porous media after rinsing with a NMR invisible fluid, and analyzing the NMR measurements to extract a petrophysical property.

Abstract: A method of a nuclear magnetic resonance measurement of a crushed porous media sample, including where the crushed pieces of the sample are not smaller than the pore size of the porous media, the surfaces of the sample are wet with a liquid and the pores of the sample are saturated with a fluid, subjecting the sample to a centrifugal force, performing a nuclear magnetic resonance measurement of the sample, and determining a petrophysical property of the sample from data acquired from the acquisition scan.

Abstract: A method of determining the identity of a petroleum coke sample including obtaining a nuclear magnetic resonance (NMR) measurement of the sample, determining a relaxation decay value of a fluid in the sample from the NMR measurement, comparing the relaxation decay value to relaxation decay values of known petroleum coke materials in a reference group to determine whether the petroleum coke is one of the known materials.

Abstract: In a magnetic resonance method, a localizing magnetic field gradient (GL) is determined suitable for acquiring a first resonant species magnetic resonance localized to a first sampling region (Rm1). A second sampling region (Rm2) defined by the localizing magnetic field gradient for a second resonant species magnetic resonance is determined. The second sampling region is spatially shifted from the first sampling region due to different gyromagnetic ratios of the first and second resonant species magnetic resonances. At least the second sampling region is displayed together with an image (62) of a subject disposed in the main magnetic field.
