Gridding and surface modeling.
Grid models are essential in modeling reservoirs. Good grid models require good input and well tuned algorithms.
In this exercise we will use as input seismic interpretation lines and closed stick faults. There are seven interpretation sets including the seabed. The reservoir has six horizons. The bottom four have fault lines as input while the top two don't use any faults.
Exercise
Grid a time surface from seismic interpretation and no faults.
- Display 02_Time data > Interpretation lines > 02BasePliocene and 02_Time data > Faults > 02BasePliocene.
- Apply the command Simple points and lines gridding
- Click Update window to get the project window as the grid window.

Exercise
Grid a time surface from seismic interpretation and closed stick faults.
- Display 02_Time data > Faults > 07SilurianFaultInt_Polygons. This is how the fault polygons comes from Kingdom. They must be edited.
- Use Edit points and lines to remove the blobs. See Case study - Gridding of seismic interpretation data with faults.
- The correct edited fault lines are in 02_Time data > Faults > CorrectedClosedFaults. Use this if you don't have time to complete the editing.
Tips when editing fault lines with _blobs_
- To remove the blobs just delete the two extra points in the blobs.
- Apply the command Gridding > Gridding points, lines and faults.
