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

Figure 2

CT scanning image presentation for Mount Elbert core section. 54 x-y slices are obtained from the scanning process which are 3 mm deep in the z direction (left). It takes 2.7 seconds to scan each slice, with an additional 10-second processing time per slice. The 54 slices are reconstructed to produce a y-z slice showing the length of the core (right) and calibrated to give density values. Scan shown here is of the Mount Elbert core after original hydrate has been dissociated, but before laboratory hydrate formation. Parts A and B of the core are indicated.
