Description
Summary:We developed a novel in situ chamber to investigate the relationship between gas hydrate crystal morphology and gas permeability in a glass micromodel that mimics marine sediment. This high-pressure experimental chamber was able to use a thin glass cell without high pressure resistance. The formation of methane hydrate (MH) in the glass micromodel was observed in situ. We investigated the relationship between the MH growth rate and the degree of super cooling ΔT. In addition, we successfully performed the in situ observation of both hydrate morphology and gas permeability measurement simultaneously.
