Figure 2
The evolution of the oil shale sample used during one of the experiments: on the top row the volume rendering of vertical sections of the whole sample are shown for the sample at ambient temperature (`Baseline'), at 13.8 MPa of confining pressure and 5.5 MPa of pore pressure at 375°C (`High P and T'), and after depressurizing and cooling the sample (`After decompression'). In the bottom row, equivalent horizontal slices from the top part of the sample (as marked in figure) are displayed. |
