lithologic assessment
The lithologic assessment module evaluates the quality of a lithologic model on an individual material basis. It works by shifting the realization probabilities toward the minimum or maximum plume bounds for a selected material, producing an output field that reflects a conservative or aggressive interpretation of material extent.
The assessment procedure is:
- Select the material to be assessed.
- Choose a Min Max Confidence Equivalent value (e.g., 95%). A value of 50% produces results equivalent to the nominal kriged model; higher confidence values (90%+) show greater deviation from the nominal.
- Select the direction (Min or Max) to shift toward.
- Choose the nodal and cell data components to include in the output.
Ports
| Direction | Name | Type | Description |
|---|---|---|---|
| Input | Indicator Grid Data | Realization | Information required for direct exporting of indicator grid data. |
| Output | Output Field | Field | The main output field representing geologic materials. |
| Output | Deviations Field | Field | A field containing deviation values by which the data has been shifted. |
Properties
| Property | Type | Description |
|---|---|---|
| Allow Run | Boolean | Controls whether the module will run when applications are loaded or data changes. When on, the module runs automatically on load or when Execute is pressed. When off, the module will not run unless Execute is pressed. |
| Execute | Button | Forces the module to run. If pressed and the application is saved, the module will also run when the application is next loaded. |
Shift Settings
| Property | Type | Description |
|---|---|---|
| Material | Choice | Controls which material is used for assessment. The available options are populated from the connected indicator grid data. |
| Min Max Confidence Equivalent | Double | Realization deviations from the nominal kriged results will be constrained to lie within the equivalent Min/Max (plume) bounds. Must be between 50% and 99.995%. A value of 50% is equivalent to the nominal kriged result. |
| Direction | Choice: Min, Max | Controls whether the assessment shifts toward the minimum or maximum plume bound. |
Data To Export
| Property | Type | Description |
|---|---|---|
| Geologic Nodal Data | Multi-select: Layer Thickness, Depth, Elevation | Selects which data components to generate for the output field on a node-by-node basis. |
| Geologic Cell Data | Multi-select: Material ID, Geo Layer | Selects which data components to generate for the output field on a cell-by-cell basis. |
| Probability | Boolean | When enabled, exports a data value describing the probability of each cell or node being the chosen material. |
| Probabilities By Material | Boolean | When enabled, exports a data value describing the probability of each cell or node being each of the different materials. |
