Bild Photo:Typical oil drilling rig at the German Oil Museum in Wietze. Incidentally, the first oil wasn’t drilled in the United States or Azerbaijan, but in Germany in Wietze, a town between Celle and Hamburg. That’s why the company headquarters of a global leader in the manufacture of drill bits are still located in Celle today.
