Total density of the rock and saturating fluids:
where
m_t – total mass of rock element,
V_t – total volume occupied by the rock element
m_t.
The bulk density
\rho_B is measured in
\rm \big[ 10^3 \cdot \frac{kg}{m^3} \big] = \big[ \frac{g}{cc} \big].

\rho_B = \phi_e \, \rho_f + V_{sh} \rho_{sh} + V_m \rho_m = \phi_e \, \rho_f + V_{sh} \rho_{sh} + (1 - \phi_e - V_{sh}) \rho_m |

\rho_f = s_{xo} \rho_{mf} + (1-s_{xo}) ( s_w \rho_w + s_o \rho_o + s_g \rho_g ) |

\rho_m = \sum_i V_{mi} \rho_{mi} |
