NGHs deposits with excess gas or water were both recoveried by depressurization. Water saturation and depressurization range are key factors for NGHs dissociation. Larger depressurization range accelerates NGHs dissociation for excess gas deposit. The obvious water mobility in excess water deposits hinders methane gas output.
