• 3) Couples additional lengths of drill rod as bit advances.
• 4) Changes drill bits as needed.
• 5) Pours water into well or pumps water or slush into well to cool drill bit and remove drillings.
• 6) Retrieves lost equipment from bore holes, using retrieval tools and equipment.
• 7) Records drilling progress and geological data.
• 8) Fabricates well casings.
• 9) Lubricates machine, splices worn or broken cables, replaces parts, and builds up and repairs drill bits.
• 10) Drives or guides truck-mounted equipment into position, levels and stabilizes rig, and extends telescoping derrick.
• 11) Inspects core samples to determine nature of strata, or takes samples to laboratory for analysis.

Activities:

• 1) Controlling Machines and Processes — Using either control mechanisms or direct physical activity to operate machines or processes (not including computers or vehicles).
• 2) Monitor Processes, Materials, or Surroundings — Monitoring and reviewing information from materials, events, or the environment, to detect or assess problems.
• 3) 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.
• 4) Handling and Moving Objects — Using hands and arms in handling, installing, positioning, and moving materials, and manipulating things.
• 5) Identifying Objects, Actions, and Events — Identifying information by categorizing, estimating, recognizing differences or similarities, and detecting changes in circumstances or events.
• 6) Operating Vehicles, Mechanized Devices, or Equipment — Running, maneuvering, navigating, or driving vehicles or mechanized equipment, such as forklifts, passenger vehicles, aircraft, or water craft.
• 7) 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.
• 8) Judging the Qualities of Things, Services, or People — Assessing the value, importance, or quality of things or people.
• 9) 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.
• 10) Documenting/Recording Information — Entering, transcribing, recording, storing, or maintaining information in written or electronic/magnetic form.
• 11) Getting Information — Observing, receiving, and otherwise obtaining information from all relevant sources
• 12) Inspecting Equipment, Structures, or Material — Inspecting equipment, structures, or materials to identify the cause of errors or other problems or defects.
• 13) Making Decisions and Solving Problems — Analyzing information and evaluating results to choose the best solution and solve problems.

Abilities:

• 1) Control Precision — The ability to quickly and repeatedly adjust the controls of a machine or a vehicle to exact positions.
• 2) 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.
• 3) 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.
• 4) Static Strength — The ability to exert maximum muscle force to lift, push, pull, or carry objects.
• 5) Near Vision — The ability to see details at close range (within a few feet of the observer).
• 6) 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).
• 7) 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.
• 8) Visualization — The ability to imagine how something will look after it is moved around or when its parts are moved or rearranged.
• 9) 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.
• 10) Extent Flexibility — The ability to bend, stretch, twist, or reach with your body, arms, and/or legs.
• 11) Visual Color Discrimination — The ability to match or detect differences between colors, including shades of color and brightness.
• 12) Finger Dexterity — The ability to make precisely coordinated movements of the fingers of one or both hands to grasp, manipulate, or assemble very small objects.

  13) Spatial Orientation — The ability to know your location in relation to the environment or to know where other objects are in relation to you.

• 14) Explosive Strength — The ability to use short bursts of muscle force to propel oneself (as in jumping or sprinting), or to throw an object.
• 15) Response Orientation — The ability to choose quickly between two or more movements in response to two or more different signals (lights, sounds, pictures). It includes the speed with which the correct response is started with the hand, foot, or other body part.
• 16) Far Vision — The ability to see details at a distance.
• 17) Trunk Strength — The ability to use your abdominal and lower back muscles to support part of the body repeatedly or continuously over time without ‘giving out’ or fatiguing.
• 18) Reaction Time — The ability to quickly respond (with the hand, finger, or foot) to a signal (sound, light, picture) when it appears.
• 19) Problem Sensitivity — The ability to tell when something is wrong or is likely to go wrong. It does not involve solving the problem, only recognizing there is a problem.
• 20) Perceptual Speed — The ability to quickly and accurately compare similarities and differences among sets of letters, numbers, objects, pictures, or patterns. The things to be compared may be presented at the same time or one after the other. This ability also includes comparing a presented object with a remembered object.

Knowledge:
