Soil model for hydrate-bearing sediments at East Nankai Trough

What is it about?

The prospects for gas production from methane hydrates have greatly improved since hydrate deposits were found to exist in sandy sediments. Heterogeneity is a very important feature of natural hydrate‐bearing sediments. In order to carry out accurate numerical simulations of the Eastern Nankai Trough gas production test, an advanced soil model is proposed in this study to better represent heterogeneous structure of the hydrate‐bearing sediments.The numerical simulations using the advanced model suggested more accurate results than the results determined from previous models. This study, as part of MH21 research program, Japan, offered important insights for offshore methane hydrate gas production in Eastern Nankai Trough, Japan.
