PORE 2-8.2: Salt Cavern Modeling and Simulation
The development of salt caverns for compressed air and hydrogen storage is experiencing significant growth. Ensuring the safe and efficient operation of these storage systems requires a thorough understanding of the mechanical stability of salt caverns under varying operational conditions. This can be achieved through numerical simulations, validated by benchmarking against laboratory and field observation data. This course will address many of the challenges associated with simulating salt caverns, many of which are also relevant to porous reservoir modeling. Participants will gain insights into the complexities of these systems and the methodologies for tackling them effectively.
Attendees will gain in-depth knowledge and hands-on experience in mechanics modeling and simulations, with a focus on salt caverns and their relevance to porous media. The course covers the fundamental concepts of salt rock mechanics and constitutive modeling, including guidelines for parameter calibration. These concepts are directly applicable to porous rock mechanics as well.
Participants will explore mathematical and numerical formulations for nonlinear mechanics in detail. The course also addresses the application of appropriate boundary conditions consistent with in-situ cavern loads.
A key feature of the course is hands-on practice with the open-source simulator SafeInCave, where attendees can apply the theoretical concepts learned. Participants will learn how to create various geometries and meshes, configure input files, and run diverse scenarios using SafeInCave.
By the end of the course, participants will be encouraged to develop their own constitutive models and simulations for salt rock mechanics. This collaborative approach will allow for comparison and discussion of results, enhancing understanding and application of the concepts.
