Layering
Layering
After subzone modeling, the target model only have one layer for each zone, which cannot appropriately describe the heterogeneity of a reservoir. Therefore, creating layers in each zone is important. There are 4 layering methods:
• Number of Layers: Number of layers for each zone. The thickness of each layer belonging to the same zone is the same.
• Proportion: Define the individual percentage of layer thickness to the zone thickness. For example, 1,2,1 means there will be 3 layers, and the middle layer has a thickness twice as large as the top and base layers.
• From Top: Define the thickness of layers. From top to base, the software creates layers with the same thickness.
• From Base： Define the thickness of layers. From base to top, the software creates layers with the same thickness.

Steps to perform Subzone Modeling in GES:
· Finish Fault Modeling, CornerPoint Gridding, Horizon Modeling and subzone modeling
· Go to Model pane → Click the grid just created → Click Horizon Modeling on Structure Modeling ribbon Bar → Select Layering Method → set Number for each method according to Method Description → Click Layering
