The pay is high (my friends earned about 12k/month) but it is dirty, dangerous work. You are isolated for weeks or months at a time. Drug use is extremely common, and your safety and even life often depends on the clear thinking and detail-orientation of someone who is hungover or high or both. There will be no internet access, although there is probably a communal television with satellite access. Many workers lose much of their money gambling: you can not participant and be isolated, or participate and lose, or participate and win and risk physical interventions.
My mom wouldn't let me go. :)
