Map FAQ

The following are common questions about working in the Map window.

What should I do when the well symbols on the map are missing?

First, try to restore the well symbols in Windows.

If the well symbol font is missing from the fonts directory, or the well symbols fail to appear in the preview window, then you must reinstall the well symbol font file.

1. Browse to the root of your Divestco Geophysical Applications CD.
2. Right-click on the wells_.ttf file and select Copy.
3. On your Windows Explorer menu bar, select Control Panel.
4. Right-click the Fonts folder and select Paste.
5. Double-click the Fonts folder to view the font files.
6. Double-click the well symbol font file.
7. Close your map, then open it again. The well symbols should appear.

How do I select a different color pallet for either the Map or Seismic windows?

Color pallets are stored in the WinPICS Profiles folder, and they have a*.CS extension.

1. Right-click on the color bar, and select Open Color Set.
2. Select a new color set from the list. The map or seismic section will dynamically update.

• Click <Make Default> in the Select Color Set dialog box to make the new color set the default color set for every time you use WinPICS .

When I open my project, why can't I see any of my 2D lines on the map?

2D lines and 3D area outlines are displayed independently of each other on the map. Make sure 2D Line and 2D Labels are selected on the Seismic tab of the Layer Manager bar.

Why aren't the hotkeys working?

Hotkeys are case sensitive. Make sure Caps Lock is turned off on your keyboard.

I have overlapping 2D lines and 3D areas in my project, and my cursor only tracks the data on top. How can I select the data beneath to view the seismic?

You can use the <b> hot key to push a seismic item from an overlapping line or area to the back.

1. Hover the cursor over the item of interest on the map until the line or area name displays on the taskbar at the bottom left corner of the Map window.
2. Press the <b> hot key to push that item to the back. The map now displays the underlying line or area name on top.

• 10 = 10 ms below the flattened event. -10 = 10 ms above the flattened event.
4. Click <Apply>.

When I rotate a fence or line, why doesn't it stay centered as it rotates on the map?

The fence or line does stay centered. However, it may not look in the Map view as though it is rotating around a fixed point. This is because as the fence or line rotates, the number of traces before and after the pivot point may vary depending on how close the pivot point is to the edge of the 3D volume. Seismic always displays from the left side of the window, so it will look as though the center is moving. Furthermore, sometimes the bins in 3D projects are not square, which distorts the appearance of the rotation. However, if you look at the red vertical pivot point in the Seismic view, you can see that the pivot bin does not change.
