Why would major oil companies like Shell, Schlumberger and Exxon Mobil hire physics graduates and physicists? So I'll be starting my physics degree course this fall and I've heard plenty of people saying that a physics degree would definitely open doors to careers at oil companies. I don't know if it's true because as far as I've heard, these companies usually hire more engineers then physicists. Also, how would a physicist contribute to an oil company if he or she is hired? Physics graduates typically don't have adequate engineering skills compared to their engineer counterparts so what would they do at oil companies?
