Fault Response Modelling
Fault Response Modelling
Boundary element modelling of fault displacement and geomechanical response in surrounding fracture systems.
The Fault Response Modelling module validates structural interpretations by simulating stress perturbations around faults and identifying highly fractured zones. It uses a boundary element method with triangular elastic dislocations to efficiently model complex faulting scenarios and assess deformation.
Resulting stress and strain fields—alongside outputs from MOVE’s Strain Capture tools—are used to predict fracture orientation and evaluate failure potential by resolving shear and normal stress components across faults and fractures.

Fault Response Modelling
Fault Response Modelling simulates fault displacement and stress–strain distribution using an analytical triangular dislocation method in an elastic half-space. This enables realistic representation of complex fault geometries, depth effects, and interactions with surrounding rock, including salt bodies and igneous intrusions.
Key capabilities
Model displacement from regional stress fields or element-level inputs, including pressure-driven deformation around reservoirs.
Calculate stress, strain and displacement in surrounding rock volumes with defined mechanical properties.
Resolve shear and normal stress to assess fracture stability, failure potential and optimal orientations using Coulomb Stress.
Generate and validate fracture sets against observed data, including angular misfit analysis across modelling workflows.
Model fracture interaction and strain transfer within Discrete Fracture Networks using Master Faults.
Perform Slip Zone Modelling (Jeyakumaran, 1992) using stress-driven or user-defined traction inputs.
Filter and visualise fractures based on stability and failure criteria to highlight critical zones.
