Gas production from heterogeneous hydrate-bearing sediments by depressurization in a large-scale simulator

Large-scale simulation can improve the understanding of production behaviour from natural hydrate deposits, especially involving heterogeneous hydrates. In this work, a heterogeneous hydrate bearing sample formed from dissolved gas was depressurized in a 200 L simulator. Gas production along with fluid migration were investigated. 42.7% of the total methane gas in the reactor was produced, and water saturation in the sediment was only reduced...
