- •
Effective and absolute permeability were measured using natural sediment cores.
- •
Experimental results were compared to logging data.
- •
Effective permeability was in the range of 1–100 md for hydrate-bearing sediments.
- •
The change of permeability, potentially caused by gas production, was analyzed.
