Abstract
Techniques for determining a geologic property of a rock sample include (i) measuring a mass of a processed rock sample that includes a solid matrix and a fluid entrained within the solid matrix; (ii) measuring, using nuclear magnetic resonance (NMR), a volume of the fluid entrained within the solid matrix; (iii) measuring, using a gas porosimeter, a volume of the solid matrix of the processed rock sample; (iv) measuring, with a mercury immersion porosimeter, a bulk volume of the processed rock sample; and (v) determining, based at least on the measured volume of the fluid, the measured volume of the solid matrix, and the measured bulk volume, at least one of a bulk density, a grain density, or a porosity of the processed rock sample.
