Two-dimensional model of transport phenomena in sedimentary basins by finite element method

Thesis/Dissertation:

Abstract

A finite element method is applied to a two-dimensional numerical model of transport phenomena occurring in the sedimentary basins during their formation. The physics used -conservation laws, Darcy`s law, compaction laws for porous media, evolution laws for thermal and hydrodynamical coefficients- is that which is used in the THEMIS model, already developed at the French Petroleum Institute. The flow problem is written in variational form, whose main unknown is the fluid pressure. The most important difficulties encountered are relative to the domain evolution (compaction, sedimentation, erosion) and highly permeable sediments such as sands. The complexity of the medium deformation is numerically described by a moving mesh whose movement is linked to that of the solid material and which is composed of quadrangles and triangles. Thermal phenomena are also modeled. The same approach as that used for the resolution of the fluid problem is applied to solve the heat equation. Many tests and comparisons with finite volume method were performed. They showed a good numerical and physical behaviour of the finite element method. This method is better adapted than the other one for modeling heterogeneous and geometrically complicated geological media. The study of a North Sea geological cross-section showed the model`s  More>>
