What type of information does ' Well penetration ' provide?

Description:
What type of information does ' Well penetration ' provide and where do I go to get this information.       

Solution:
Well penetraion is the annotation of the penetration of a borehole in a horizon. 
The number that is posted is the time at which the borehole penetrates the horizon.

Well penetration is setup under Basemap > Define > Wells > Well appearance.
Toggle on the button marked "penetrations. 

Tips of what to look for if you can't post the penetration points in basemap:

-  Make sure you have selected a symbol for the penetraton

-  Check to make sure that the well has had a velocity applied to it that goes
    down to at least the same time of the horizon being posted.

-  Make sure that the deviation survey has valid points.

-  Horizon must go over the point of penetraton, if not, it will not post.  If
   you snapped a horizon and it has holes in the interpretation over the point
   of penetration, you will need to pick your horizon over that hole.  A sure
   way to check is to bring up a Seis2D/3DV window, post the well, post the
   horizon and see if it crosses.  If there is a fault over that area, it will
   not post the penetration.

-  You can only post penetration points on a time map, not an amplitude map.
