Computational Geomechanics Using FLAC, FLAC3D, and UDEC
The main objective of this course is demonstrating the implementation of numerical modeling and geomechanics simulation in reservoir engineering. The course focuses on the practical applications of numerical modeling for simulation and analysis of geomechanics problems such as wellbore stability, geothermal analysis, flow analysis, and hydraulic fracturing. Several topics including elasticity and plasticity of the rock medium, constitutive models, stress distribution, and permeability considerations will be discussed. The simulation procedure of isotropic and transversely isotropic medium and faults and discontinuities will be presented. Commercial programs for geomechanics modeling will be introduced, and finite difference, finite element, and distinct element methods for numerical modeling will be described. Different software tools including FLAC, FLAC3D, and UDEC will be considered for conducting simulations.

What our participants say about the Computational Geomechanics course…
“Anyone with solid background knowledge, looking for practical experience in continuum and discontinuum geomechanical modelling, will find the course a very robust and hands-on introduction to three of Itasca’s well-known numerical simulators. Working for a state mining regulator, I had so far relied on theoretical knowledge and common sense when it came to assessing study results obtained with the help of one of the programs. Thanks to Dr. Zamiran’s thorough lectures, the opportunity to ask questions and the chance to experiment with basic models of my own, I now have a much better understanding of the practical workflows, options and pit-falls in such undertakings. The course will be particularly useful to anyone planning to professionally use one of the programs in the near future.”

“I am a reservoir engineer dealing with the technical operational aspects of underground gas storage. It was really helpful to learn about the usage of the widely used numerical software packages in the industry and how they can handle praxis-oriented geomechanical problems on a theoretical basis. During the course, I learned how to investigate in the future my technical questions on my own with the help of technical descriptions of applied programs. Many thanks to our instructor and course trainer. With his help now I am ready to continue my technical education in the field of geomechanical modeling by the application of industry-leading numerical simulators.”

“As a beginner in FLAC3D & UDEC, I found the course content and the examples explained very helpful. The course material and the recorded lectures were made accessible at all times during the course. Dr. Zamiran was very kind to offer individual Zoom sessions to answer questions and help with the software. I strongly recommend the course if you are using FLAC, FLAC3D, or UDEC in your research or projects.”
