3. DESCRIPTION OF PROBLEM OR FUNCTION
The numerical model CCC (conduction-convection-consolidation) solves the heat and mass flow equations for a fully, liquid-saturated, anisotropic porous medium and computes one-dimensional (vertical) consolidation of the simu- lated systems. The model has been applied to problems in the fields of geothermal reservoir engineering, aquifer thermal energy storage, well testing, radioactive waste isolation, and in situ coal com- bustion. The code has been validated against analytic solutions for fluid and heat flow, and against a field experiment for underground storage of hot water.

4. METHOD OF SOLUTION
The model employs the Integrated Finite Diffe- rence Method (IFDM) in discretizing the saturated porous medium and formulating the governing equations. The sets of equations are sol- ved by an iterative solution technique. The vertical deformation of the medium is calculated using the one-dimensional consolidation theory of Terzaghi.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM
Maximum of -
12 materials
It is assumed that -
(a) Darcy's law adequately describes fluid movement through fractured and porous media.
(b) The rock and fluid are in thermal equilibrium at any given time.
(c) Energy changes due to the fluid compressibility, acceleration and viscous dissipation are neglected.
(d) One-dimensional consolidation theory adequately describes the vertical deformation of the medium.

8. RELATED AND AUXILIARY PROGRAMS
CCC is one of a set of five geo- thermal codes. The others are: ANALYZE for multiwell, multirate well test parameter determination (NESC Abstract 891); SHAFT79 for two- phase geothermal reservoir simulation (NESC Abstract 893); TERZAGI for isothermal fluid flow and subsidence (NESC Abstract 894); and WELBORE for steady and transient geothermal wellbore flow (NESC Abstract 895).
