Creating a "Geologic" Map with Contours from a GSB Model
(Note: In all scripts and command lines that follow, a backslash ( \ ) at the end of a line indicates that the current line is continued on the line that follows. When creating the script or typing the command line, these lines should be entered as one continuous line without the backslash.)
How is it possible to calculate a grid of the thickness of a layer in a GSB model?
A thickness grid is accessible through the export to GRIDGENR format found in the Export for Simulator Preprocessors program. (Since horizons of a GSB model are made up of several pieces of other grids (one grid per fault block), it is difficult to create a thickness grid by simply subtracting the horizons in the Formula Processor.) Enter the desired sequence file in the Export for Simulator Preprossors program (available via Utilities -> Data Export and select the desired fault blocks and zone. Then select Calculate -> Export for GRIDGENR. Change "Delete Script" on the Calculate window to "Script only", enter a script name, and select the "Now" button. This setting just creates the script, without performing the calculation. In the script displayed on the screen, you will see a line that looks similar to:THICKNESS layer3.thk.2grdThis line identifies the thickness grid as "layer3.thk.2grd". Then later on in the script, you should see a line similar to the following:
ev_clean layer3.top.2grd \Edit this script file to remove the thickness file name from the ev_clean line so that this line looks like the following:
layer3.thk.2grd
ev_clean layer3.top.2grd
Then run the script by typing the script name at the UNIX command prompt. The resultant thickness grid, in this case, layer3.thk.2grd, represents the thickness of the layer.
