Local Update

Local Update is to update model locally while keeping the rest of the model unchanged. This could be extremely useful when updating the entire model is unaffordable. In general, Local Update is suitable for the cases where only a specific volume of a model needs to be updated, e.g., a new well is drilled and only the model around the well needs to be updated.

 

Structure Updating

The structure model local updating allows for a local update on horizon model, which alters grids as well. The input for structure model local updating includes well picks, point, line and surface data, fault polygons, and model boundary. Users may define the local update boundary by using a polygon; GES could also automatically identify the update boundary from the input data.

Steps to perform Structure Updating in GES:

· Go to Model pane → Click the model grid you want to updating

· Go to Geology & Modeling Scenario → Structure Modeling → Local Updating

· General Settings → Select data for Well Picks → Select data for Lines → Well Adjustment Settings → Regions Settings → Fault Lines Settings → Click OK

 

Block Well Updating

Block well local update is done in the Block Well window, users can update by adding and well settings.

Steps to perform Block Well Updating in GES:

· Go to Model pane → Click the model grid you want to updating

· Go to Geology & Modeling Scenario → Reservoir Modeling → Block Wells

· Choose block well you want to updating for BW Property → Click Add → Select Data Type and Data Name → Settings → Select → Click OK

 

Property Updating

Facies model local update allows users to update model within the volume defined by users. In GES, updating range are determined by 3 regions, well region, facies region, polygon region, you can choose to use intersection region, or use union region.

Steps to perform Property Updating in GES:

· Go to Model pane → Click the model grid you want to updating

· Go to Geology & Modeling Scenario → Reservoir Modeling → Facies Modeling → Select data for BW Property Name → Input Model Name → Local Update Settings → Select updating region → Click OK

· Go to Geology & Modeling Scenario → Reservoir Modeling → Petrophysics Modeling → Select data for BW Property Name → Input Model Name → Local Update Settings → Select updating region → Click OK
