- Apply green technologies or techniques, such as the use of coiled tubing, slim-hole drilling, horizontal drilling, hydraulic fracturing, or gas lift systems.
- Operate specialized equipment to remove obstructions by backing off or severing pipes by chemical or explosive action.
- Perforate well casings or sidewalls of boreholes with explosive charges.
- Examine unserviceable wells to determine actions to be taken to improve well conditions.
- Monitor sound wave-generating or detecting mechanisms to determine well fluid levels.
- Insert detection instruments into wells with obstructions.
- Install pressure-control devices onto wellheads.
- Line drilled holes with pipes, and install all necessary hardware, to prepare new wells.
- 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.
- Maintain records of footage drilled, location and nature of strata penetrated, materials and tools used, services rendered, and time required.
- 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.
- Count sections of drill rod to determine depths of boreholes.
- Maintain and adjust machinery to ensure proper performance.
- Direct rig crews in drilling and other activities, such as setting up rigs and completing or servicing wells.
- Weigh clay, and mix with water and chemicals to make drilling mud.
- Start and examine operation of slush pumps to ensure circulation and consistency of drilling fluid or mud in well.
- Clean and oil pulleys, blocks, and cables.
- Monitor progress of drilling operations, and select and change drill bits according to the nature of strata, using hand tools.
- Repair or replace defective parts of machinery, such as rotary drill rigs, water trucks, air compressors, and pumps, using hand tools.
- Locate and recover lost or broken bits, casings, and drill pipes from wells, using special tools.
- Cap wells with packers, or turn valves, to regulate outflow of oil from wells.
- Remove core samples during drilling to determine the nature of the strata being drilled.
- Bolt together pump and engine parts, and connect tanks and flow lines.
- Plug observation wells, and restore sites.
- Position and prepare truck-mounted derricks at drilling areas specified on field maps.
- Lower and explode charges in boreholes to start flow of oil from wells.
- Inspect safety equipment, such as harnesses, belts, and lifelines, before use.
- Line drilled holes with pipes, and install all necessary hardware, to prepare new wells.
