Pros
There can be good money to be made if you care to sacrifice your life to be in the remote locations where they are drilling.
Cons
You will be bunking with people you may not want to know, let alone living with them. They will be your family whether you like it or not. The young leads often get there by someone they know or by someone which liked them and were groomed. They turn out to be very bad leaders. The office personnel only listen to the leaders on site. If anything goes wrong, the accusers don't go into the office with you so they don't have any skin in the game to try and make things work. They can say whatever they won't to the office and the office with be the ones taking action. Subordinates have very little sway no matter what the circumstances.
