Methane Hydrate Distribution from Prolonged and Repeated Formation in Natural and Compacted Sand Samples: X-Ray CT Observations

Figure 4

Methane hydrate formation at location 111 mm in the Mount Elbert core. (a) Test ME1.1—pressurization. (b) Test ME1.2—cooling. Slices in both figures were taken at 10-minute intervals after the initial onset of hydrate formation was observed in the pressure/temperature data for each test.
