Transcript:Whether working around the globe at mines and drilling locations, or in labs analyzing data, geological and petroleum technicians help scientists identify locations that indicate the presence of potential resources such as oil and gas, minerals, or metallic ores. In the field, geological and petroleum technicians use sophisticated equipment, such as seismic instruments, to gather geological data. Under the supervision of geologists and engineers, they gather rock and soil samples, and work with environmental scientists and technicians to monitor the environmental impact of drilling and mining. In laboratories, these technicians analyze samples for evidence of hydrocarbons, useful metals, or precious gemstones. They analyze data, produce maps, and write reports detailing a site’s potential for further exploration, or explaining a current site’s productivity. Most geological and petroleum technicians work standard full-time business hours, except when they’re working in the field. Fieldwork is conducted outdoors in all types of weather, sometimes for weeks at a time and at times in remote locations. Many technicians work in mining-related operations, oil and gas extraction, and for engineering services. Jobs in this field typically require an associate’s degree, or two years of college courses in applied science or science-related technology. Some highly technical jobs require a bachelor’s degree.

What does this information tell me?

Outlook information can tell you whether a career is expected to be in demand in the future—that is, whether there are likely to be job openings if you choose this career. Please note that this does not account for the impacts of the current pandemic. Many occupations are likely to have very different outlooks due to the rapidly changing economy. When new outlook information is developed, it will be reflected here.

Careers can have one of three outlooks:

  • A Bright outlook means new job opportunities are very likely in the future
  • An Average outlook means that a small number of new job opportunities are likely in the future (less than an 8 percent increase)
  • A Below average outlook means new job opportunities are less likely in the future

You can also view local job listings in this field by clicking "Find job openings" above. This can help you see if local businesses are hiring—another way of looking at demand.

What is the source of this information?

This information comes from O*NET Bright Outlook occupations and My Next Move career outlook designations (based on Bureau of Labor Statistics Employment Projections 2022-32). It is only available at a national level, so even if you selected a state, you’ll only see this information for the whole country.
