Topic:
How to create a depth map using marker velocities.

Description:

Solution:
Prerequisites: Wells must have a checkshot or DVT associated.  Markers are 
loaded/created in depth.

1.) Select > Markers > Velocity.
   - Select tops
   - Select source(s) and exit.

2.) Grid markers: Edit > Grid Contour, adjust parameters and exit.

3.) Grid time horizon: Edit > Grid Contour, adjust parameters and exit.

4.) Multiply time and velocity grid by selecting Grid Operations > Combine.
   - Toggle Grid operation to multiply.
   - Scale #1 units leave to none. (defaults to grids units).
   - Scale for Grid #2 (velocity) leave to 1.
   - Scale #2 units leave to none. (defaults to grids units)
   - Scale for Grid #1 (time) type in .5 to compute one-way time.
   - Toggle Input Grid to List.
   - Type name in Resultant Surface Name.
   - Type description in Title, optional.
   - Grid #1 Fault Handling and Grid #2 Fault Handling need to be set if 
     you have fault traces.
   - Grid Extent Handling - determine which grid extent to use and Exit.
   - Select the velocity grid, select yes to make current data.
   - Select the time grid, select yes to make current data.
   - Select the contour icon to display.
