The channel modeling tools in GVERSE Geo+ allow the interpreter to view channel truncations and unconformity relations anytime during the interpretation and see the results on the fly, not only in the Map View but also in the Cross Section and in 3D Visualization. For the tools to work properly, and in accordance with the geology of the area, it is important to set certain parameters in GVERSE Geo+ before proceeding:

1. Activate a GeoGraphix Project.
   
   
    
2. Launch GVERSE Geo+ from the ProjectExplorer toolbar, by clicking on the GVERSE Geo+ module icon.
   
   
   
   The Open Interpretation window displays.
3. Select an existing interpretation or select Create New. Click Open.
   
   

Setting Up Surface Type and Form

1. From the GVERSE GEO+ toolbar, select Strat Column Manager under the Tools tab.
   
   
   The Stratigraphic Column Manager window displays.
    
2. To set up Surface Type and Form, verify that the surface of interest (the channel unconformity) is set as an Unconformity in the Type column.
   
   
   Note: Make sure all surfaces are in the correct chronological order. This is critical; otherwise the Geomodel will not behave as expected.
    
3. In GVERSE Geo+, go to Geo Surface Model Properties >> Surfaces tab, check the channel unconformity, in this case MORROWVALLEYBASE, is set as a Channelform surface.
4. Select the surface and check the Channel checkbox under the Surface Properties group box on the right.
   
   
   Note: The overlying flooding surface V7 FS is also defined as an unconformity. This is necessary in order for the channel to truncate against it based on the Unconformity Networking setup.

Setting Up Surface Network and Constraints

1. In the GeoSurface Model Properties window, go to the Surface Constraints tab and set up the surface constraints with the flooding surfaces constrained.
   
   
   Note: V7 FS is set up as the master constraining surface. This is done so that the underlying marine flooding surfaces that are partially cut out by the channel conform to the continuous V7 FS surface and therefore intersect the channel margins in the appropriate stratigraphic positions. This setup is appropriate as long as all the flooding surfaces/marine markers are interpreted to
