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.

6. TYPICAL RUNNING TIME

The sample problem requires about 12 seconds  of CP time on a CDC7600 for compilation and execution.

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).
