Topic:
How can you output amplitude values at borehole surface penetrations?

Description:
There are times that you not only need time values from surface penetrations but
amplitudes as well.  You need to document amplitude values and graph them at the
borehole penetrations.      

Solution:
1. Get surface penetration times from Basemap - Tools - Surface penetrations.

2. Save these as markers - Save button on surface penetrations menu.

3. Grid these markers under Basemap - Gridding. 
	Set parameters to small spacing and low grid coverage.
	You should get grid values only at penetration points.
	If there is any interpolation between points, decrease spacing.

4. Save the grid under a new surface.
	Basemap - Gridding - save as menu - click on create surface
	type in name for new surface and OK
	select the new surface and save the grid under the new surface.

5. Convert this grid to horizon under IESX Data Manager - Interpretation -
   Surface - rid to horizon. 

6. Extract amplitudes on this horizon.

Now you have amplitude values only at the borehole penetration locations.
These can be posted on Basemap or written out under Interpretation - Export and
taken to a graph.
