DOI: 10.1016/j.marpetgeo.2018.08.016
Abstract: Abstract Gas and water permeability through hydrate-bearing sediments essentially governs the economic feasibility of gas production from gas hydrate deposits. Characterizing a reservoir's permeability can be difficult because even collocated permeability measurements can vary by… read more here.
