Under the Results-Report sub-tab, the tables for Saturation exponent, Cementation exponent, Resistivity index, and RelativeElectrical Conductivity are shown for the chosen saturation rates (here, 0, 0.25, 0.50, 0.75, and 1), which are approximated as best as possible (here, 0, 0.246104, 0.510196, 0.749864, and 1).
The Cementation Exponent is used to determine how porosity affects resistivity in fully water saturated conditions and it indirectly influences the interpretation of the resistivity index.
The saturation-dependent Relative Electrical Conductivity of the fluid is shown in the tables, where each row stands for one saturation level. The values of the whole electrical conductivity tensor at each saturation step are given in the columns.
In the example above, the entries , , for the computation in Z-direction are given, the other values are unknown as the computations were not carried out.
Plots tab
In the Results-Plots subtab, the values of the Relative Electrical Conductivity table are shown in a graph. Also, the Layered Potential in the computed directions is given.
Electrical Conductivity Plot
The values of the electrical conductivity in all selected Computational Directions at the different saturation levels are shown in a graph.
On the left, the Post-Processing Widget allows you to fine-tune the Electrical Conductivity plot. Collapse the Post-Processing Widget by pulling it to the left.
On the left side in the expandable Graph Options, you can modify the way the diffusivity graph is displayed by selecting
the Graph Type (El. Conductivity over Saturation or Saturation over El. Conductivity),
the Phase Selection (Invading Fluid or Displaced Fluid),
the El. Conductivity Unit (Effective conductivity in S/m or Index),
and the Saturation Unit (Relative or Absolute).
Click Apply to change the graph shown according to the options selected.
Layered Potential
In the Layered Potential tab for each computational direction the potential in each layer is shown in a graph. The saturation values for each graph correspond to the saturation of the invading fluid. The settings made under the Graph Options do not apply for these plots, but the axis settings and graph styles can be changed under Plot Options.
Influence of Thin Films
We redo the computations, but without adding thin film voxels and compare the plots of the resistivity index using a combined gdr file. Observe that for the structure without thin film voxels there is no conductivity above an oil saturation of about 50%.
