Abstract
Water permeability in hydrate-bearing sediments is a key parameter in gas production affecting the effective depressurization boundary from a wellbore and contributing heat transport associated with fluid flow. The experimental measurement of water permeability in the presence of hydrates is associated with many difficulties such as dynamic hydrate dissolution and formation during fluid flow and long induction time. In this study, we formed tetrahydrofuran (THF) hydrates in a core-scale chamber to explore water permeability as a function of hydrates. Wave velocities during the permeability measurement were also measured. The results show that water permeability decreases as hydrate saturation increases. Shear and compression wave velocities increase with increasing hydrate saturation, but the velocity decreases a little during the repetitive permeability measurement at a given hydrate saturation.
