Three-dimensional (3D) finite model simulating hanging wall deformation during fault inversion highlights areas of increased differential stress that indicate locations for additional subseismic faulting and fracturing.
Map-views through 3D finite element models that simulate stress state (A) before and (B) after well bore is pressurized. Hot colors show high tensile stress.
Southwest Research Institute® (SwRI®) has developed effective approaches to building and analyzing geomechanical models of complex geologic structures and processes, including:
- Extensional fault-tip monoclines
- Contractional fault-related folds
- 3D subsurface stress development following faulting and erosion
- 2D and 3D simulations of induced hydraulic fracturing
