Gas Production from Hydrate-Bearing Sediments: The Role of Fine ...

Websediment lithology plays a major role in determining where hydrate beds form (Garg et al., 2008). This is due to the coarser grained sediments having much higher permeability values than Þne grained pelagic clays. When upwelling methane gas enters the HSZ, it dissolves into the pore spaces between and within sediment grains WebWhereas the only visible hydrate sample (FC4) has not found any bioclast in the sediments. Based on the Raman data and the XRD analysis, the gas hydrates demonstrate typical structure I (sI) hydrates, with cage occupancies of methane molecules higher than 99.3% in large cages and 81.5%-91.4% in small cages, respectively.
