hello, my name is asaf and i work as a gis operator in israel. 

I would like to know more about the way oil and gas companies (abroad) use the viewshed and observer point.

for what reason exactley?
and do they calculate building height or only use the DEM?

If anyone can refer me to a source i'll be much obliged.
