Tasks and Duties
- Bolt together pump and engine parts, and connect tanks and flow lines.
- Cap wells with packers, or turn valves, in order to regulate outflow of oil from wells.
- Clean and oil pulleys, blocks, and cables.
- Connect sections of drill pipe, using hand tools and powered wrenches and tongs.
- Count sections of drill rod in order to determine depths of boreholes.
- Dig holes, set forms, and mix and pour concrete, for foundations of steel or wooden derricks.
- Direct rig crews in drilling and other activities, such as setting up rigs and completing or servicing wells.
- Line drilled holes with pipes, and install all necessary hardware, in order to prepare new wells.
- Lower and explode charges in boreholes in order to start flow of oil from wells.
- Monitor progress of drilling operations, and select and change drill bits according to the nature of strata, using hand tools.
- Observe pressure gauge and move throttles and levers in order to control the speed of rotary tables, and to regulate pressure of tools at bottoms of boreholes.
- Position and prepare truck-mounted derricks at drilling areas that are specified on field maps.
- Push levers and brake pedals in order to control gasoline, diesel, electric, or steam draw works that lower and raise drill pipes and casings in and out of wells.
- Remove core samples during drilling in order to determine the nature of the strata being drilled.
- Start and examine operation of slush pumps in order to ensure circulation and consistency of drilling fluid or mud in well.
- Weigh clay, and mix with water and chemicals to make drilling mud.
- Locate and recover lost or broken bits, casings, and drill pipes from wells, using special tools.
- Maintain and adjust machinery in order to ensure proper performance.
- Maintain records of footage drilled, location and nature of strata penetrated, materials and tools used, services rendered, and time required.
- Plug observation wells, and restore sites.
- Repair or replace defective parts of machinery, such as rotary drill rigs, water trucks, air compressors, and pumps, using hand tools.
- Train crews, and introduce procedures to make drill work more safe and effective.
