How to create depth maps in BasemapPlus

Description:
 

Solution:
In order to create a depth grid in Basemap Plus you must construct a velocity
grid by which you will multiply your time grid.  The result will be the depth 
grid.

The steps are as follows.


1) Grid a time horizon and save the grid;

2) Post boreholes;

3) Create and save surface penetrations (markers) of the gridded surface in
   Tools > Surface Penetrations;

4) Post penetrations (markers) in TVDSS in Post > Interpretation > Markers and
   grid them in Gridding, then save the grid;

5) Post penetrations (markers) in TWT in Post > Interpretation > Markers and
   grid them in Gridding, then save the grid;

6) Using Binary Operations, divide grid 4 by grid 5 to generate a velocity grid;
   Save this velocity grid as well.

7) Using Binary Operations, multiply velocity grid 6 by time grid 1 to generate
   your depth grid.  

Note:  Watch the units for your depth map.  They are now in thousands of feet 
       or meters.
