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 five have fault lines as input while the top two one don't use any faults.

Grid a time surface from seismic interpretation and no faults. - Display interpretation lines from 02_Time data > Interpretation lines > 02BasePliocene.
- Apply the command Simple points and lines gridding
- Click Update window to get the project window as the grid window.
- Set x and y increment to 500.

| title | Grid window for Course B1 |
|---|
| - xmin = -188000, xmax = -47500; ymin = 7864500, ymax = 7959000
- Using grid increment 500 this gives as size of grid: number in rows: 282 , number in columns: 190
- It is a relatively small grid, but useful in a course and the size of the project is kept reasonable low.
|
- Use gridding algorithm Parabolic (default).
- Check in for *Use two steps gridding". Grid increment will be automatic calculated if blank.
- Set moving average as gridding algorithm for 1. step.
- Click Execute. The result will be written to the same folder.
- Click OK and save the panel with all parameters.
- Create a new folder for interpretation grids and cut/paste the result grid into this folder.

| title | Grid menus using faults |
|---|
|
- The grid menu when faults are included is Gridding points, lines and faults. This menu can also be used when there is no faults, but the one we used is a simpler alternative.
