Experiments were performed with a 12 mm long and 1.2 mm diameter sapphire tube at pressures above 12 MPa and temperatures of 5°C. The tube was filled with sand (mean grain size 0.29 mm, maximum grain size 0.7 mm, minimum grain size 0.063 mm and modal grain size distribution). Distilled water, which was saturated with methane, was pumped through the sand at a constant flow rate of 0.75 ml/min. Gas hydrates eventually formed from the gas saturated solution.
