Скачать или смотреть GeoDict Seminar - Digital Rock Physics for Geomechanics: Predicting Elasticity and Deformation

How can you accurately predict the geomechanical behavior of reservoir rocks without the high costs and destructive nature of physical lab tests? This technical webinar 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.

Key insights and workflows demonstrated in this seminar:

🔵 From Scan to Simulation: Understand the foundational DRP workflow, which starts with a micro-CT scan of a rock plug and results in a 3D model ready for geomechanical analysis.

🔵 Predicting Rock Elasticity: Learn how to set up simulations in ElastoDict to compute the complete stiffness tensor and determine essential properties like Young's modulus and Poisson's ratio.

🔵 Visualizing Stress & Strain: Go beyond simple numbers by analyzing 3D stress and strain fields to identify how forces concentrate within the rock's microstructure, particularly at critical grain-to-grain contacts.

🔵 Advanced Grain Contact Modeling: Discover how to improve prediction accuracy by using the Quantitative Seismic GeoApp to explicitly identify and modify grain contacts, a crucial factor affecting rock stiffness.

🔵 Simulating Rock Failure: Follow a step-by-step guide to predict the complete stress-strain curve, including setting mineral-specific failure criteria to simulate rock failure under both unconfined and confined compression.

🔵 Answering Key Industry Questions: The session concludes 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.
