Investigating natural methane hydrate from the Black Sea.
Natural gas hydrates (NGH) are crystalline materials in which water molecules form networks where gas molecules are trapped. These NGH have very large gas storage capacity and methane NGH are found worldwide in marine sediments on continental margins. Their formation mechanisms in such complex porous medium are still poorly known. In the case of clay-rich sediment like those encountered in the Black Sea, the question of the accumulation of hydrate in the interlayer remains elusive. Only few studies have been devoted to the plausible formation of NGH in sediment nanopores (natural or synthetic). Recent IN1 experiments (8-12 feb. 2021) showed different inelastic spectral signatures for the various synthetic clay/silica matrix sediments at various salt concentrations. In September 2021, an IFREMER oceanic cruise, GHASS 2, is scheduled with the aim to collect natural hydrate-bearing sediments from the deep-sea floor of the Black Sea. The goal of this continuation experiment is to acquire inelastic spectra of these natural gas hydrates in order to evaluate the validity of the ¿lab-made hydrate bearing¿ as model systems reproducing the geo- and physical- chemistry properties of NGH.
