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+MAM, performing two meter-scale laboratory experiments of gas hydrates for production by depressurization, replicating the gas hydrate deposit in the Ulleung Basin, East Sea, South Korea. The first experiment with a...
