Dude, why are you limiting yourself to oilfield work? Right now aviation is taking off like a rocket. I work for Bell Helicopter and we're hiring college graduates like crazy that have unrelated degrees to aviation. I was laid off from oil patch work during one of the two month downturns and got a job a Bell that has opened the doors for my future, doors that were closed before because oil field work is like blacksmithing is to rocket science.
