Structural Modeling: Fault Modeling Process (1) The Structural modeling processes include the use of the Fault modeling and the Pillar gridding processes together to create a skeleton framework. 1. Define a Fault model. Before you start Fault modeling, define and name a model that will store the fault model and all 3D grids related to that fault model. 2. Activate the new empty model and activate the Fault modeling process.
Structural Modeling: Fault Modeling Process (2) 3. Right-click the input data (fault sticks) in the Input pane and select Convert to faults in fault model. 4. Specify to build a key pillar on every 5th fault stick and set the max search distance to the nearest neighbor pillar.
Structural Modeling: Key Pillars The new faults are stored in the Faults model folder named after their input. The faults consists of adjustable key pillars. Many shape points are defined by the geometry selected before automatically converting data to faults in the fault model (in this case, three point listric geometry). Top shape point

Structural Modeling: Automated Trimming of Faults
Pillars after Make simple grid, vertical.
Pillars after Corner Point gridding, with projected path of pillars were they do not extend to the top.
The Key pillars generated by Corner point gridding must run through the complete model area. Cut/extend pillars against a surface or a given constant. 1. Select Processes pane > Fault modeling. On the Operations tab, set the Top and Base limits, given by 2D grids. 2. Choose All or Only selected pillars. Cut and extend to the limits and click OK.
Structural Modeling: Automatic Connection of Faults Automatic fault connection: Faults close to each other, not cutting through, and faults overlapping each other must be connected to build a proper lattice for the Pillar gridding process. Normally used with clean orthogonal fault data. Also used to find problems with fault intersections. After those have been located and edited, auto connection can be run again.
Remove distance: Removes pillars less Extend distance: Searches for pillars within the given distance and connect them. than the given distance from the connection.
