Claim 8:
9. A non-transitory computer readable medium storing instructions executable by a computer processor, the instructions comprising functionality for:
receiving, for each of a plurality of rock samples:
a bulk density,
a grain density,
a fluid density, and
a scanning electron microscope (SEM) image of a cross-section;

determining a first porosity value based, at least in part on, the bulk density, grain density, and fluid density;
determining a second porosity value from the SEM image,
