Horizon Picking in VuPAK

Overview

You will be working with the BEG Project which is in the Demo data set included in the 8.6 installation DVD. This tutorial will show you how to use the horizon pickers that are exclusive to VuPAK, mainly SurfaceHunt and VolumeHunt. The 2d3dPAK horizon pickers can also be used in VuPAK but are discussed in the 2d3dPAK Horizon Interpretation tutorial. You will also interpret a fault in a chair display.

1. Select Project > VuPAK to open the Select Viewing Area dialog box.

Picking Horizons

SurfaceHunt

In this section you will pick a horizon using VuPAK Surface Hunt by clicking on one point in the volume.VuPAK Surface Hunt horizon picking in the animation volume accepts a single seed pick and searches in all directions from your seed pick until it has examined and tried to pick every trace in the seismic volume for your selected amplitude.

1. From the previous section you should have an Animation Volume loaded in the VuPAK viewing area.

2. With the Select cursor click the Inline face of the volume and drag using the SuperScope. Stop at Line 50. Use the Inline Position window to note your line position.

3. Locate Crossline 100 by moving the Select cursor (no clicking) on the Crossline and noting the crossline position in the Status bar located at the bottom of the VuPAK window.

19. Click OK to close the Color Editor.

SurfaceHunt Picking Considerations

When picking in the SurfaceHunt mode, be sure to consider the following:• Horizons can be picked on an Animation Volume.

• If you choose another seed point for the same horizon, the new picks will overwrite the existing picks.

• Display the horizon on the Base Map and use Horizons > Polygon Erase to delete any errant picks—erase non-manual picks only, manual picks only and both non-manual and manual picks.

KINGDOM 8.6 13

EXIT

• Notice that the picked horizon does not extend over the portion of the volume that was not displayed in the Vupak window. To extend the horizon from Inline 50 to Inline 1, “pull” the volume from Inline 50 to Inline 1. Revisit step 5. and select the 1.08 Horizon for the active surface and pick the horizon from Inline 50 to Inline 1. You can rotate the cube to see it from the opposite side and push the face past the end of the picked horizon. Look at the 1.08 Horizon displayed on the base map.

Figure 13 Warning dialog box, pick deletion options for Polygon Erase

• Horizon picking is not available in the Oblique Plane or Oblique Cut modes.

• In the Chair Cut mode, the seed pick may be interpreted on any of the chair surfaces. The seed pick cannot be made on the outside faces of the volume.

VolumeHunt

In this section, you will pick a channel on a rendered voxel volume using VuPAK VolumeHunt in the Golden Project in the Demo data set which is included in the installation 8.6 DVD. 1. Open the Golden Project by selecting Project>Open Project and navigate to the Demo data

sets.

2. Choose SMT as the Author.

3. Launch VuPAK by selecting Project>VuPAK.

4. Be sure to turn ON New VuPAK Session.

5. In VuPAK click the Display Seismic Objects icon .

6. When the Display Seismic Objects window appears:

14 KINGDOM 8.6

EXIT

If there is no bricked volume, choose the unbricked data volume. A window will appear asking if you want to create a bricked volume. Click Brick to create the bricked data set. The Generate Brick Volume dialog box will appear (Figure 14).

In the Generate Brick Volume dialog box highlight Amplitudes and click OK.

Select a location for the output volume and click OK.
