A geological or petroleum technician attempts to discover valuable resources by analyzing geological samples of minerals and soil. They support engineers and scientists in extracting and exploring natural sources like crude oil, minerals, and the detection of natural gas. Geological technicians indicate the potential for exploration to determine chemical or physical properties and test geological samples to check if they meet required quality standards.

How to Become a Geological or Petroleum Technician
To become a geological or petroleum technician, you usually need an associate’s degree in applied sciences or a certification in science or technology at a minimum; however, most employers prefer a bachelor’s degree. Some schools have internships and hands-on programs where you can gain experience while attending school.-however, some employers may also offer apprenticeships.
While attending colleges, universities, or a vocational school, seek programs in geosciences, mining, or related subjects, such as geographic information systems (GIS). These programs will include geology, math, computer science, chemistry, and physics coursework.
In addition, some geological and hydrologic technicians pursue certifications in Occupational Safety & Health Administration (OSHA) Hazardous Waste Operations and Emergency Response Standard (HAZWOPER). This includes skilled training in health hazards, personal protective equipment, site safety, and additional state or national regulations. There are also voluntary certificates from the American Institute of Hydrology (AIH).
Job Description of a Geological or Petroleum Technician

A geological or petroleum technician determines the content and characteristics of soil samples soil and the minerals are analyzed and tested using testing and laboratory equipment. They analyze samples of earth or liquid to assist engineers and scientists in determining if the chemical or physical properties meet the requirements needed.
Geologists assist in hydrographic, geological, geochemical, geophysical, and/or oceanographic surveys. They also assist in exploratory drilling, underground mine surveys, well logging, and prospecting field trip operations. They assemble and prepare cross sections, sketches, and geological maps to figure out information from section descriptions, well logs, and aerial photos that assists in the overall analyzation of a project.
A geological or petroleum technician should have knowledge of electronics and computers that would include chips, circuit boards, hardware and software, and the programs they must use on-the-job. They need to have knowledge of chemistry, geography, and physics. Most geological or petroleum technicians work in laboratories or offices. However, they also spend time in the field. Most technician’s work full-time.
Job satisfaction is one of the biggest reasons to become a Geological or Petroleum Technician. They love their jobs! Scientists and Engineers respect them for helping find valuable resources, predicting earthquakes, and saving lives! They are in high demand, which means jobs are plentiful.
