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.
