Validation of strongly coupled geomechanics and gas hydrate reservoir simulation with multiscale laboratory tests

We validate a coupled flow-geomechanics simulator for gas hydrate deposits, named T+M A M , performing two meter-scale laboratory experiments of hydrates production by depressurization replicating the deposit in Ulleung Basin, East Sea, South Korea. The first experiment with sand-only specimen is 1D 1 m-scale test based on excess method, which represents grain coating growth. On other hand, second 3D 1.5 water method sand–mud alternating layer system, representing pore filling measure and displacement at top different levels. In particular, exhibits high coupling strength substantial deformation induced incompressibility deformability specimen. For validation, we match pressure, flow rate, between experimental data numerical results. Thus, identify that reliable simulator, can be applied to fields both permafrost deep oceanic deposits strongly geomechanics systems. This validation also implies simulators same formulation as validated when individual are stable reliable.
