Landmark DecisionSpace® Geosciences Isatis Plug-in | Data export
Property export to Isatis – Demo contents:
One simulation of porosity was run in DSG and displayed in the Cube view.
We export this property and the associated blocked wells in Isatis.
The export is done interval per interval in a (I, J, K ) flat space.
The data appears in the Isatis tree after a refresh of the database.
We filter the well logs to mask the invalid samples as it is done in DSG.
We use an Isatis recorded workflow.
We visualize the exported data in the Isatis 3D viewer, setting some displayed parameters for a better visual comparison with the DSG’s cube view.
We now compute geobodies using Isatis geobodies identification algorithm. The geobody computation is done by retaining only very high porosity cells (i.e. with more than 25%
porosity).This operation is done interval by interval.
We look now at the geobodies corresponding to the first interval in the Isatis 3D viewer. The geobodies are ranked per size with an integer code for each geobody. Code 0 corresponds to the background matrix which needs filtering, 1 to the biggest geobody, 2 to the second biggest and so on.
The 3D view represents the 10 biggest geobodies in color with the remaining ones in white.
To check that the geobodies correspond to high porosity bodies we can overlay on top the porosity field using a transparency setting. The high porosities correspond indeed to the geobodies.
We then export the geobodies property inside DSG using the Import from Isatis window. We just need to specify the Isatis’s grid and property and the system retrieves automatically the DSG’s grid it is associated to.
In the cube view we could have a look at the results and compare with the porosity field using some subset and opacity settings. As before the geobodies correspond to high porosity values.
