Test and analyze geological samples, crude oil, or petroleum products to detect presence of petroleum, gas, or mineral deposits indicating potential for exploration and production, or to determine physical and chemical properties to ensure that products meet quality standards.

Assemble, operate, and maintain field and laboratory testing, measuring, and mechanical equipment, working as part of a crew when required. Collect and prepare solid and fluid samples for analysis. Compile and record testing and operational data for review and further analysis. Plot information from aerial photographs, well logs, section descriptions, and other databases. Prepare notes, sketches, geological maps, and cross sections. Prepare, transcribe, and/or analyze seismic, gravimetric, well log or other geophysical and survey data. Test and analyze samples in order to determine their content and characteristics, using laboratory apparatus and testing equipment. Adjust and repair testing, electrical, and mechanical equipment and devices. Assess the environmental impacts of development projects on subsurface materials. Collaborate with hydro-geologists in order to evaluate groundwater and well circulation. Participate in geological, geophysical, geochemical, hydrographic or oceanographic surveys, prospecting field trips, exploratory drilling, well logging or underground mine survey programs. Participate in the evaluation of possible mining locations. Inspect engines for wear and defective parts, using equipment and measuring devices. Supervise well exploration and drilling activities, and well completions.

Mechanical -- Knowledge of machines and tools, including their designs, uses, repair, and maintenance. 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. Mathematics -- Knowledge of arithmetic, algebra, geometry, calculus, statistics, and their applications. 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.

Science -- Using scientific rules and methods to solve problems. Speaking -- Talking to others to convey information effectively. Quality Control Analysis -- Conducting tests and inspections of products, services, or processes to evaluate quality or performance. Operation and Control -- Controlling operations of equipment or systems. Equipment Selection -- Determining the kind of tools and equipment needed to do a job. Coordination -- Adjusting actions in relation to others' actions. Mathematics -- Using mathematics to solve problems. Writing -- Communicating effectively in writing as appropriate for the needs of the audience.

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). Near Vision -- The ability to see details at close range (within a few feet of the observer). Wrist-Finger Speed -- The ability to make fast, simple, repeated movements of the fingers, hands, and wrists. Oral Expression -- The ability to communicate information and ideas in speaking so others will understand. Written Expression -- The ability to communicate information and ideas in writing so others will understand. 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. Deductive Reasoning -- The ability to apply general rules to specific problems to produce answers that make sense. Number Facility -- The ability to add, subtract, multiply, or divide quickly and correctly. 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. Control Precision -- The ability to quickly and repeatedly adjust the controls of a machine or a vehicle to exact positions.

Getting Information -- Observing, receiving, and otherwise obtaining information from all relevant sources. Documenting/Recording Information -- Entering, transcribing, recording, storing, or maintaining information in written or electronic/magnetic form. Identifying Objects, Actions, and Events -- Identifying information by categorizing, estimating, recognizing differences or similarities, and detecting changes in circumstances or events. Communicating with Supervisors, Peers, or Subordinates -- Providing information to supervisors, co-workers, and subordinates by telephone, in written form, e-mail, or in person. Controlling Machines and Processes -- Using either control mechanisms or direct physical activity to operate machines or processes (not including computers or vehicles). Analyzing Data or Information -- Identifying the underlying principles, reasons, or facts of information by breaking down information or data into separate parts. 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. Processing Information -- Compiling, coding, categorizing, calculating, tabulating, auditing, or verifying information or data. Interpreting the Meaning of Information for Others -- Translating or explaining what information means and how it can be used. Repairing and Maintaining Electronic Equipment -- Servicing, repairing, calibrating, regulating, fine-tuning, or testing machines, devices, and equipment that operate primarily on the basis of electrical or electronic (not mechanical) principles.
