Integrated geomechanical services to assess fault propensity to slip
Our philosophy is to provide subsurface teams with what they need to confidently assess the propensity to slip of faults in their area of interest. This typically involves integrating geomechanical modeling, seismic-based fault interpretation, fault modeling, and stress-based slip analysis into a single, consistent workflow. Our approach is designed to deliver fast, cost-effective evaluations while preserving the geological and mechanical controls that govern fault behavior under stress. Try our FracSlip3D app if you already have a fault geometry you want to test.
Geomechanical model construction
We build geomechanical models that define the in-situ stress state, pore pressure, and rock mechanical properties using well logs, well tests, seismic data, and regional constraints, providing a consistent foundation for critical stress analysis.
Fault Interpretation from seismic data
We interpret faults directly from seismic data, ensuring accurate fault geometry, orientation, dip, and spatial continuity required for reliable stress-based reactivation analysis. Structural seismic attributes are used where appropriate to enhance fault detection and continuity.
Fault modeling
Interpreted faults are converted into geologically consistent fault surface models that capture local variations in azimuth and dip along the fault planes and allow spatial sampling of stresses and mechanical properties from geomechanical model.
QC and use of existing geomechanical models
When client geomechanical models already exist, we perform a detailed quality control to evaluate assumptions, internal consistency, and applicability, and integrate them directly into the fault reactivation workflow when appropriate.
QC of client fault interpretations
When fault interpretations are provided by the client, we review and quality-check fault geometry, orientation, and continuity against the original seismic data to ensure suitability for quantitative stress and slip analysis.
Critical stress analysis
Using the geomechanical model and fault geometries, we perform 3D critical stress analysis along fault surfaces, resolving stresses onto fault planes and quantifying slip tendency and pressure sensitivity under current or perturbed stress conditions, including fluid injection scenarios. Calibration with local earthquake data. Results are also useful in studies of reservoir compartmentalization by faults.
