Stress Analysis

Display and evaluate the effect of present-day and palaeo stress states on slip and stability of faults and fracture systems in 3D.

The Stress Analysis module enables rapid visualization and evaluation of 3D stress states and potential fault and fracture activity.

This information can then be used to build and analyse a wide range of scenarios encountered in reservoir and mine planning, CO₂ storage, waste disposal and other engineering applications, where it is essential to understand the likely failure envelope of key structural features.

Evaluate the risk of leakage within reservoir seals, predict mineralisation potential and geotechnical failure. Test a series of principal stresses and pressure profiles through depth, taking into consideration hydrostatic, pore and lithostatic pressures.

Stress Analysis

Compute slip tendency, dilation tendency, fracture stability, slip stability, retention capacity and leakage factor of planes and lines.
Visualize and evaluate critically stressed planes in a 3D View. Any orientation data selected on the stereonet plot or Mohr diagram is simultaneously selected in the 3D model.
Visualize shear and normal stress values for ease of use on the Mohr diagram when moving the cursor over the stereonet plot.
Colour map the current displayed stress attribute that is plotted on the stereonet plot and Mohr diagram at a specific depth.
Define and display pore pressure profiles.
Quickly estimate which fracture sets and fault planes are more likely to fail or reactivate from the colour map: warmer colours indicate the faults more favourably orientated to failure in a user-defined stress state.
