How to create an isopach map using well markers and a horizon.

Description:
Well markers are in depth and the horizon is in time.        

Solution:
1) Convert the markers to Seismic Time Picks (STP) in Marker Data Manager.

2) Post markers on the basemap with the index set to Seismic Time Picks (TWT)
   Note: Boreholes have to be posted for markers to post on the basemap.

3) Grid the STP values and save the grid.

4) Post and grid the horizon 
   Note: Recommend using the same gridding parameters as used for the markers.
 
5) Save the horizon as a grid.

6) Use Gridding Operations => Binary => to subtract one grid from the other and
   save as the isopach.
