Abstract

Water permeability in gas hydrate bearing sediments is a crucial parameter for the prediction of
gas production scenarios. So far, the commonly used permeability models are backed by very few
experimental data. Furthermore, detailed knowledge of the exact formation mechanism leads to
severe uncertainties in the interpretation of the experimental data. We formed CH4 hydrates from
a methane saturated water solution and used Magnetic Resonance Imaging (MRI) to measure time
resolved maps of the three-dimensional gas hydrate saturation. These maps were used for 3D
Finite Elements Method (FEM) simulations. The simulation results enabled us to optimize
existing models for permeabilities as function of gas hydrate saturation.
