Gas Production From Oceanic Class 2 Hydrate Accumulations

Gas hydrates are solid crystalline compounds in which gas molecules are lodged within the lattices of ice crystals. The vast amounts of hydrocarbon gases trapped in hydrate deposits in the permafrost and in deep ocean sediments constitute a promising energy source. Class 2 hydrate deposits are characterized by a hydrate-bearing layer (HBL) that is underlain by a saturated zone of mobile water (WZ). This study investigated three methods of gas production that used vertical-well designs.
