What is the job outlook for the next decade?
The job outlook for geoscientists, which includes geologists, is projected to be about as fast as the average for all occupations. According to the U.S. Bureau of Labor Statistics (BLS), employment of geoscientists is projected to grow 5 percent from 2023 to 2033. This is expected to result in about 2,200 openings for geoscientists each year, on average, over the decade, with many of these openings arising from the need to replace workers who retire or transfer to other occupations.
Several factors are expected to drive demand. The need for energy, environmental protection, and responsible land and resource management will continue to require geological expertise. Geologists will be involved in finding and managing traditional and alternative energy sources (like geothermal and sites for wind turbines), assessing water resources, monitoring and remediating environmental contamination, and advising on land use and infrastructure development. There's also a noted concern about a potential shortage of geologists due to retirements in the coming years, which could create opportunities for new graduates.
It's important for aspiring geologists to stay informed about industry trends and potentially consider specializations in high-demand areas. The American Geosciences Institute provides valuable workforce information and reports.
These courses touch on areas of growing importance, such as environmental management and resource exploration, which influence the job outlook.

Can I transition from oil/gas to environmental geology?
Yes, transitioning from the oil and gas industry to environmental geology is often feasible, as many core geological skills are transferable. Geologists in the oil and gas sector develop strong expertise in areas like subsurface mapping, well log interpretation, seismic data analysis, sedimentology, and structural geology, all of which can be valuable in environmental applications. For instance, understanding subsurface fluid flow is critical in both petroleum geology and hydrogeology (a key component of environmental geology).
To make a successful transition, geologists may need to acquire additional knowledge or certifications specific to environmental regulations, site assessment techniques, remediation technologies, and environmental geochemistry. Taking specialized courses, attending workshops, or even pursuing a graduate certificate in environmental geology can be beneficial. Networking with professionals in the environmental sector and highlighting transferable skills on a resume are also important steps. Many environmental consulting firms value the strong technical foundation that geologists from the oil and gas industry often possess.
These courses focus on environmental aspects and water resources, which would be beneficial for someone transitioning into environmental geology.

What are the risks in geological fieldwork?
Geological fieldwork, while often rewarding, can involve various risks depending on the location and nature of the work. Physical hazards are common and can include slips, trips, and falls on uneven or steep terrain, rockfalls from unstable cliffs or slopes, and injuries from using tools like rock hammers. Working in remote areas can mean limited access to emergency services and communication. Wildlife encounters, ranging from insects and snakes to larger animals, can also pose risks in certain environments.
Weather-related hazards are another significant concern, including heatstroke, hypothermia, lightning strikes, and flash floods. Working in specific environments like active volcanoes, earthquake-prone regions, or coastal areas with strong tides presents unique dangers. Furthermore, fieldwork in old mines or contaminated sites can involve risks from unstable structures or exposure to hazardous materials. Strict adherence to safety protocols, thorough planning, appropriate training, use of personal protective equipment (PPE), and awareness of potential hazards are essential to mitigate these risks.
These courses, while not solely focused on geological fieldwork safety, offer skills in navigation and wilderness awareness that are highly relevant to managing risks in the field.
