Micromechanical computational modeling of reservoir compaction and surface subsidence. (English)
0 references
The authors generalize computational dual porosity models developed for the case where the solid matrix undergoes elastic deformations. Variational formulation and the corrosponding two-level finite element approximations are proposed to discretize the dual porosity system. Numerical simulations of a compacting oil reservior and its subsidence at the surface are performed to show numerically a correlation between the microstructure and macroscopic hereditary creep phenomena governing the delayed secondary compression.
