Methane hydrate is considered as a promising energy resource for the near future. To predict the gas productivity from the methane hydrate in the subsea sand-sediment, it is important to know effective permeability accurately of the sediment bearing

Estimation of surface area of methane hydrate in sub-seabed sand sediment is important to predict the production rate of methane gas. The surface area depends on the morphology of hydrate in the sediment: i.e., how the methane hydrate exists in the s

A numerical method system to estimate the permeability of sand sediments, at a microscopic scale, was developed. Initially, 3D geometrical representations of the sand grains are reconstructed from a series of 2D X-ray CT scans of real sand grains. 2D
