A Rotary Drill Operator sets up or operates a variety of drills to remove petroleum products from the earth and to remove core samples for testing during oil and gas exploration.

The Rotary Drill Operators has several tasks that they need to perform in their job functions. The following is a brief summary of the required tasks:

Rotary Drill Operator Tasks:

• The Rotary Drill Operator observes pressure gauges and moves control to regulate speed of rotary table and pressure of tools at bottom of boreholes.
• The Rotary Drill Operator selects and changes drill bits according to nature of strata, using hand tools.
• The Rotary Drill Operator pushes levers and brake pedals to control draw works which lowers and raises drill pipe and casing in and out of wells.
• The Rotary Drill Operator withdraws core barrel from hole and extracts core from barrel.
• The Rotary Drill Operator connects sections of drill pipe, using hand tools and powered wrenches and tongs.
• The Rotary Drill Operator counts sections of drill rod to determine depth of borehole.
• The Rotary Drill Operator positions truck-mounted derrick at drilling area specified on field map.
• The Rotary Drill Operator examines operation of slush pumps to ensure circulation and consistency of mud (drilling fluid) in well.
• The Rotary Drill Operator examines drillings or core samples from bottom of well to determine nature of strata.
• The Rotary Drill Operator fishes for and recovers lost or broken bits, casing and drill pipes from well, using special tools.
• The Rotary Drill Operator caps well or turns valves to regulate outflow of oil from well.
• The Rotary Drill Operator keeps record of footage drilled, location and nature of strata penetrated, and materials used.
• The Rotary Drill Operator repairs or replaces defective parts of machinery, using hand tools.
• The Rotary Drill Operator lowers and explodes charge in borehole to start flow of oil from well.
