You need to go to Rigzone.com and post a resume first and you need to know what you like to do. I work in Russia on an oil rig and there are also of different job out here like Mechanic, Electrician, Driller, and Electronic Tech witch is what I do. All three pay good at the top, but you have to work to get there.
