Abstract Summary
Understanding the processes and mechanisms involved in the creation and accumulation of discrete gas phases by nuclear waste disposals buried in clay formations is essential. In this work, the D-23 MAGIC and LASGIT (gas test 1) are studied based on the same methodology, modeling strategy, and material properties applied in the previous work for DECOVALEX 2019 Task A stage 1A (ENGINEER) for evaluating multiphase flow in porous media incorporating permeability heterogeneity. A coupled hydro gas 3D FEM numerical model is developed for each case by the UPC/Andra team to simulate the gas flow tests using the CODE BRIGHT software.
