Digital Rock Physics for Geomechanics: Predicting Elasticity and Deformation from Microstructures
Seminar recording
How can you accurately predict the geomechanical behavior of reservoir rocks without the high costs and destructive nature of physical lab tests? This technical online seminar demonstrates a complete digital rock physics (DRP) workflow to determine key geomechanical properties directly from micro-CT images.
Join our expert, Lobel Danicic, as he presents a simulation-first approach using the GeoDict software. Witness the entire process, from preparing a 3D digital rock model to predicting rock elasticity, simulating complete stress-strain curves, and visualizing mineral failure.
This session is essential for geoscientists, reservoir engineers, petrophysicists, and R&D managers in the energy sector who need to understand and forecast rock behavior for improved production and operational safety.
In this seminar you will learn step-by-step:
- From scan to simulation: Understand the complete DRP workflow – from micro-CT scanning to creating a 3D model ready for geomechanical analysis.
- Predicting rock elasticity: Set up simulations in ElastoDict to compute the stiffness tensor, Young’s modulus, and Poisson’s ratio.
- Visualizing stress and strain: Analyze 3D stress and strain fields to identify force concentrations and critical grain contacts.
- Grain contact modeling: Use the Quantitative Seismic GeoApp to explicitly capture grain contacts and improve stiffness predictions.
- Simulating rock failure: Predict full stress–strain curves and apply mineral-specific failure criteria.
- Answering Key Industry Questions: The session concluded with an expert Q&A, addressing topics such as modeling anisotropic materials, the effect of fluids on geomechanical properties, and how to calibrate simulations with physical experimental data – available in the recorded video.
