Abstract Burial driven recycling is an important process in the natural gas hydrate (GH) systems worldwide, characterized by complex multiphysics interactions like migration through evolving stability zone (GHSZ), competing gas‐water‐hydrate (i.e., fluid‐fluid‐solid) phase transitions, locally appearing and disappearing phases, sediment properties (e.g., permeability, reaction surface area, cap...

A coupled multiphase fluid flow and discrete fracturing model is applied to simulate bench-scale gas migration experiments on compacted bentonite. The numerical modeling based the linking of simulator TOUGH2 with a Rigid-Body-Spring Network model, which enables (lattice) representation elasticity individual fractures. evolution complex network dilatant paths modeled through opening breakage lat...
