Drilling rigs commonly operate 24 hours per day, 7 days per week with either three crews working 8 hour shifts or two crews working 12 hour shifts. Most often day crews and night crews will alternate weekly so each crew has a chance to work during both the day and night.
Once a well has been proven to produce oil, the drilling crew leave and service rig crew will come in to set up smaller service rigs. As a service rig crew member, you will work an average of 8-12 hours per day, starting in the early morning and finishing in the afternoon or early evening.
