Running the rock property model

With the Run Model form (model > Rock Properties > Run Model) you can execute a modeling run for one or more Volumes of Interest (VOI's). The result consists of a grid property which is stored in the JewelExplorer (under the Rock Properties folder) and which can be visualized in the 3D View. Note that if you want to run a variogram-based modeling method (SIS or TGS), make sure that you have assigned a variogram to the respective VOI.

To run your model

  1. Open the Run Model form and select the rock property model from the Model drop-down list.
  2. In the Volume of Interest table, select one or more Volumes of Interest (VOIs) that you want to run. The Status column indicates whether the model already contains results for the respective VOI.
  3. Set unselected VOIs to 'Undefined'   This checkbox becomes relevant when there are VOIs in the VOI table which contain run results of a previous run and which you do not intend to run this time.
    • When the box is checked, the deselected VOIs will be reset to undefined values.
    • When the box is not checked, the deselected VOIs will keep their previous run results.
  4. Simulation seed base  A randomization number that starts off the stochastic algorithm. When all parameters settings remain the same, a different seed number will produce a slightly different result. Only when all parameter settings are the same and the seed number is identical, you can reproduce the results.
    5. Uncertainty   The rock property model can be propagated as a parametric uncertainty in a probabilistic volumetric calculation with the study strip by making the 'Simulation seed base' uncertain. Click the uncertainty symbol behind the 'Simulation seed base' entry field to open the Uncertainty Parameter dialog. For how to use the controls on the dialog, see The Uncertainty Parameter dialog. For information about parametric uncertainties and how to use them in JewelSuite Subsurface Modeling, see Incorporating uncertainty in static or dynamic modeling.
  5. Realizations  The number of realizations produced by the modeling run. The realizations are stored in the JewelExplorer (under the Rock Properties folder) under one single name, with the number of realizations printed after the name, e.g. Rock Property Model 1 [1 of 3].

    6. If you ran multiple realizations, you have to use the Property Inspector to change the realization displayed in the 3D View. To do this, go to Panes > Inspector and click on the Property Inspector icon . In the Property section, under Current step, type the realization number. The 3D View is automatically updated.

  6. Re-run single realization   After QC-ing multiple realizations, you can re-run a specific realization to use as input to subsequent modeling steps (e.g. the saturation property model). If you have multiple realizations from a previous run, and you do not re-run a single realization, by default the first realization (of the suite of realizations) is used. When you re-run a single realization, it will replace all previous run results in the JewelExplorer.
    7. Uncertainty   When you perform a probabilistic volumetric calculation with the study strip (Study > Volumetrics), and you re-run a single realization, that realization is used as the reference case. If you have multiple realizations and do not re-run a single realization, the probabilistic volumetric calculation will use the first realization as the reference case.
  7. Click Apply to run the model and keep the form open, or click OK to run the model and close the form.

The Summary VOI section on the right side of the form shows the summary of the selected VOI on the left side of the form. You can export the summary of the selected VOI by clicking on Copy to Clipboard button. To export the summary of all the VOI's in your model click on Copy all VOI summaries to Clipboard.

With the Property vs Path form you can visualize one or two properties change along a predefined path. The predefined path can either be a line or a wellbore.
