One of my best buddies worked for Aztec Drilling for about 5 years. Mainly natural gas in Pennsylvania, Ohio, and WV. but often times he'd have to fly out to New Mexico and Utah to supervise short staffed crews........he hated it. He made great money but he was away from home constantly, the work was dangerous, filthy, and really hard, and all the guys you're working with are there because they can't pass background checks for other lines of work. Those guys make their money fast and most of them live even faster. Blowing it at the casino, on expensive cars, drugs/booze, and prostitutes. It's a young man's job. Turnover is incredibly high. You either get injured, age out, or end up in jail because ruffnecks gonna ruffneck. I think I posted this in the strength and conditioning forum, but a lot of guys casually blast and cruise on PEDs to keep up with the demanding nature of the work along with all of the partying.
I lived in the Permian Basin in 2012 when things were really booming. It was really wild out there. The cops, ambulances, and tow trucks were constantly busy with all of the wild shit happening and constant influx of new people trying to cash in. Felt like a Mad Max movie driving on I20 between Midland and Odessa everyday for work.
If you're over 30 and you're out there on an oil derrick breaking your back, you probably fucked up pretty bad somewhere along the way.
