Dual-porosity poroelastic modeling of generalized plane strain

A finite element solution based on the concept of dual-porosity poroelasticity is developed which enables the applications to be suitable for the fractured porous media. Using the equivalent parameters, the comparative analysis for the column consolidation and for the well pumping verify the developed dual-porosity model. Preliminary studies identify the fracture spacing, an index of the fracture density, as the influential parameter which controls the magnitudes and distributions of the coupled pore pressure and rock deformation, in particular within the near-well regions.
