Notes:
A mathematical model treating the compaction of sediments in geological basins is derived. The model is based on the principle of conservation of mass and energy, and gives a consistent and complete set of equations for compaction, pressure and temperature history of sedimentary basins.Further, the paper describes a numerical model based on the mathematical equations, derived by using the finite element method. This derivation starts with the time-discretized versions of the conservation laws of mass and energy. The result is the time-discretized equations for pressure and temperature. The numerical derivation is parallel with the mathematical deductions. By integrating these time-discretized equations spatially the element equations are obtained. Hence, the element equations are derived directly from the underlying physical laws. This approach to developing element equations in a compacting medium is believed to be new. The model has been tested successfully on some geological basins, and the results of a simulation are included at the end of the paper.
