1. A method for characterizing properties of a rock sample obtained from a subterranean formation, comprising:
performing an NMR measurement on the rock sample;
determining data characterizing matrix density of the rock sample, wherein the rock sample comprises cuttings and wherein the cuttings comprise cleaned cuttings; and
using results of the NMR measurements and the data characterizing matrix density of the rock sample to determine data representing at least one property of the rock sample.
