Good day ...
As an oil field worker, the drilling will working 24 hours. We have shift 12 hrs. 12 hrs for work and 12 hrs for rest (sleep). But if needed is possible working more than that.
Plus minus effect working in day day or night. Hot temp and cold temp always happen. Some people like working night but it not meaning no have problem. Sleepy is enemy number one. Sometime not focus because of it.
So whatever the shift, show must go on. Whatever shift you taking, rig life is unique. Your body must be in good fit. Extremely weather no compromise.
The light on picture always on. Worker always busy. So.. this is rig life
