Train crews, and introduce procedures to make drill work more safe and effective.
Observe pressure gauge and move throttles and levers to control the speed of rotary tables, and to regulate pressure of tools at bottoms of boreholes.
Count sections of drill rod to determine depths of boreholes.
Push levers and brake pedals to control gasoline, diesel, electric, or steam draw works that lower and raise drill pipes and casings in and out of wells.
Connect sections of drill pipe, using hand tools and powered wrenches and tongs.
Maintain records of footage drilled, location and nature of strata penetrated, materials and tools used, services rendered, and time required.
Maintain and adjust machinery to ensure proper performance.
Start and examine operation of slush pumps to ensure circulation and consistency of drilling fluid or mud in well.
Locate and recover lost or broken bits, casings, and drill pipes from wells, using special tools.
Weigh clay, and mix with water and chemicals to make drilling mud.
Direct rig crews in drilling and other activities, such as setting up rigs and completing or servicing wells.
