Starts and controls drilling action and lowering of well casing into well bore.
Withdraws drill rod from hole and extracts core sample.
Couples additional lengths of drill rod as bit advances.
Changes drill bits as needed.
Pours water into well or pumps water or slush into well to cool drill bit and remove drillings.
Retrieves lost equipment

Records drilling progress and geological data.
Fabricates well casings.
Lubricates machine, splices worn or broken cables, replaces parts, and builds up and repairs drill bits.
Drives or guides truck-mounted equipment into position, levels and stabilizes rig, and extends telescoping derrick.
Inspects core samples to determine nature of strata, or takes samples to laboratory for analysis.
Assembles non-truck-mounted drilling equipment, using hand tools and power tools.
Monitors operation of drilling equipment to determine changes in strata or variations in drilling.
Mechanical -- Knowledge of machines and tools, including their designs, uses, repair, and maintenance.
Engineering and Technology -- Knowledge of the practical application of engineering science and technology. This includes applying principles, techniques, procedures, and equipment to the design and production of various goods and services.
Physics -- Knowledge and prediction of physical principles, laws, their interrelationships, and applications to understanding fluid, material, and atmospheric dynamics, and mechanical, electrical, atomic and sub- atomic structures and processes.
Operation and Control -- Controlling operations of equipment or systems.
Operation Monitoring -- Watching gauges, dials, or other indicators to make sure a machine is working properly.
Equipment Selection -- Determining the kind of tools and equipment needed to do a job.
Equipment Maintenance -- Performing routine maintenance on equipment and determining when and what kind of maintenance is needed.
Multilimb Coordination -- The ability to coordinate two or more limbs (for example, two arms, two legs, or one leg and one arm) while sitting, standing, or lying down. It does not involve performing the activities while the whole body is in motion.
Control Precision -- The ability to quickly and repeatedly adjust the controls of a machine or a vehicle to exact positions.
Depth Perception -- The ability to judge which of several objects is closer or farther away from you, or to judge the distance between you and an object.
Static Strength -- The ability to exert maximum muscle force to lift, push, pull, or carry objects.
Near Vision -- The ability to see details at close range (within a few feet of the observer).
Information Ordering -- The ability to arrange things or actions in a certain order or pattern according to a specific rule or set of rules (e.g., patterns of numbers, letters, words, pictures, mathematical operations).
Manual Dexterity -- The ability to quickly move your hand, your hand together with your arm, or your two hands to grasp, manipulate, or assemble objects.
Extent Flexibility -- The ability to bend, stretch, twist, or reach with your body, arms, and/or legs.
Visualization -- The ability to imagine how something will look after it is moved around or when its parts are moved or rearranged.
Arm-Hand Steadiness -- The ability to keep your hand and arm steady while moving your arm or while holding your arm and hand in one position.
Controlling Machines and Processes -- Using either control mechanisms or direct physical activity to operate machines or processes (not including computers or vehicles).
Handling and Moving Objects -- Using hands and arms in handling, installing, positioning, and moving materials, and manipulating things.
Performing General Physical Activities -- Performing physical activities that require considerable use of your arms and legs and moving your whole body, such as climbing, lifting, balancing, walking, stooping, and handling of materials.
Monitor Processes, Materials, or Surroundings -- Monitoring and reviewing information from materials, events, or the environment, to detect or assess problems.
Operating Vehicles, Mechanized Devices, or Equipment -- Running, maneuvering, navigating, or driving vehicles or mechanized equipment, such as forklifts, passenger vehicles, aircraft, or water craft.
Identifying Objects, Actions, and Events -- Identifying information by categorizing, estimating, recognizing differences or similarities, and detecting changes in circumstances or events.
Repairing and Maintaining Mechanical Equipment -- Servicing, repairing, adjusting, and testing machines, devices, moving parts, and equipment that operate primarily on the basis of mechanical (not electronic) principles.
Judging the Qualities of Things, Services, or People -- Assessing the value, importance, or quality of things or people.
Documenting/Recording Information -- Entering, transcribing, recording, storing, or maintaining information in written or electronic/magnetic form.
Evaluating Information to Determine Compliance with Standards -- Using relevant information and individual judgment to determine whether events or processes comply with laws, regulations, or standards.
