At 38,000 square feet in size, they produced average weekly sales of $564,000 translating to sales per square foot of $777, and generated a contribution margin of approximately 6%.

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.
A crew will typically work 7 days of 12-hour day shifts, then 7 days of 12-hour night shifts, followed by 7 days off. Rig employees refer to their work period as a 'hitch.'. This is a common rotation for a hitch, but it can vary. Sometimes a rig crew works 20 days on, followed by 10 days off. A crew may also be scheduled for 2 weeks of day shifts, followed by 7 days off, followed by 2 weeks of night shifts.
