Detailed Description

This material computes internal energy (J/m^3) for a rock matrix assuming constant grain density, specific heat capacity, and a linear relationship with temperature.

To get the volumetric heat capacity of the rock in a rock-fluid system, the result must be multiplied by (1 - porosity).
