Petroleum engineers design and develop methods for extracting oil and gas from deposits below the Earth's surface. Petroleum engineers also find new ways to extract oil and gas from older wells.
Petroleum engineers typically do the following:
Oil and gas deposits, or reservoirs, are located deep in rock formations underground. These reservoirs can be accessed only by drilling wells, either on land, or at sea from offshore oil rigs.
Once oil and gas are discovered, petroleum engineers work with geoscientists and other specialists to understand the geologic formation of the rock containing the reservoir. They then determine the drilling methods, design the drilling equipment, implement the drilling plan, and monitor operations.
The best techniques currently being used recover only a portion of the oil and gas in a reservoir, so petroleum engineers also research and develop new ways to recover more of the oil and gas. This additional recovery helps to lower the cost of drilling and production.
The following are examples of types of petroleum engineers:
Completions engineers decide the best way to finish building wells so that oil or gas will flow up from underground. They oversee work to complete the building of wells—a project that might involve the use of tubing, hydraulic fracturing, or pressure-control techniques.
Drilling engineers determine the best way to drill oil or gas wells, taking into account a number of factors, including cost. They also ensure that the drilling process is safe, efficient, and minimally disruptive to the environment.
Production engineers take over wells after drilling is completed. They typically monitor wells' oil and gas production. If wells are not producing as much as expected, production engineers figure out ways to increase the amount being extracted.
Reservoir engineers estimate how much oil or gas can be recovered from underground deposits, known as reservoirs. They study reservoirs' characteristics and determine which methods will get the most oil or gas out of the reservoirs. They also monitor operations to ensure that optimal levels of these resources are being recovered.
Petroleum engineers hold about 22,800 jobs. The largest employers of petroleum engineers are as follows:
|Oil and gas extraction||26%|
|Management of companies and enterprises||20%|
|Support activities for mining||18%|
|Petroleum and coal products manufacturing||6%|
Petroleum engineers generally work in offices or at drilling and well sites. Travel is frequently required to visit these sites or to meet with other engineers, oilfield workers, and customers.
Large oil and gas companies maintain operations around the world; therefore, petroleum engineers sometimes work in other countries. Petroleum engineers also must be able to work with people from a wide variety of backgrounds, including other types of engineers, scientists, and oil and gas field workers.
Petroleum engineers typically work full time. Overtime may be necessary when traveling to and from drilling sites to help in their operation or respond to problems when they arise.

Petroleum engineers must have a bachelor's degree in engineering, preferably petroleum engineering. However, a bachelor's degree in mechanical, civil, or chemical engineering may meet employer requirements. Employers also value work experience, so college cooperative-education programs, in which students earn academic credit and job experience, are valuable as well.
Students interested in studying petroleum engineering will benefit from taking high school courses in math, such as algebra, trigonometry, and calculus; and in science, such as biology, chemistry, and physics.
Entry-level petroleum engineering jobs require a bachelor's degree. Bachelor's degree programs include classes, laboratory work, and field studies in areas such as engineering principles, geology, and thermodynamics. Most colleges and universities offer cooperative programs in which students gain practical experience while completing their education.
Some colleges and universities offer 5-year programs in chemical or mechanical engineering that lead to both a bachelor's degree and a master's degree. Some employers prefer applicants who have earned a graduate degree. A graduate degree also allows an engineer to work as an instructor at some universities or in research and development.
ABET accredits programs in petroleum engineering.
Analytical skills. Petroleum engineers must be able to compile and make sense of large amounts of technical information and data in order to ensure that facilities operate safely and effectively.
Creativity. Because each new drill site is unique and therefore presents new challenges, petroleum engineers must be able to come up with creative designs to extract oil and gas.
Interpersonal skills. Petroleum engineers must work with others on projects that require highly complex machinery, equipment, and infrastructure. Communicating and working well with other engineers and oil and gas workers is crucial to ensuring that projects meet customer needs and run safely and efficiently.
Math skills. Petroleum engineers use the principles of calculus and other advanced topics in math for analysis, design, and troubleshooting in their work.
Problem-solving skills. Identifying problems in drilling plans is critical for petroleum engineers because these problems can be costly. Petroleum engineers must be careful not to overlook any potential issues and must quickly address those which do occur.
Licensure is not required for entry-level positions as a petroleum engineer. A Professional Engineering (PE) license, which allows for higher levels of leadership and independence, can be acquired later in one's career. Licensed engineers are called professional engineers (PEs). A PE can oversee the work of other engineers, sign off on projects, and provide services directly to the public. State licensure generally requires
The initial FE exam can be taken after one earns a bachelor's degree. Engineers who pass this exam are commonly called engineers in training (EITs) or engineer interns (EIs). After meeting work experience requirements, EITs and EIs can take the second exam, called the Principles and Practice of Engineering (PE).
Several states require engineers to take continuing education courses in order to keep their licenses. Most states recognize licensure from other states if the licensing state's requirements meet or exceed their own licensure requirements. The Society of Petroleum Engineers offers certification. To be certified, petroleum engineers must be members of the Society, pass an exam, and meet other qualifications.
Entry-level engineers usually work under the supervision of experienced engineers. In large companies, new engineers also may receive formal training. As engineers gain knowledge and experience, they move to more difficult projects on which they have greater independence to develop designs, solve problems, and make decisions.
Eventually, petroleum engineers may advance to supervise a team of engineers and technicians. Some become engineering managers or move into other managerial positions. For more information, see the profile on architectural and engineering managers.
Petroleum engineers also may go into sales and use their engineering background to inform the discussion of a product's technical aspects with potential buyers and to help in product planning, installation, and use. For more information, see the profile on sales engineers.
The median annual wage for petroleum engineers is $130,850. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $78,390, and the highest 10 percent earned more than $208,000.
The median annual wages for petroleum engineers in the top industries in which they work are as follows:
|Management of companies and enterprises||$165,480|
|Oil and gas extraction||$141,570|
|Petroleum and coal products manufacturing||$128,740|
|Support activities for mining||$123,820|
Petroleum engineers typically work full time. Overtime may be necessary when traveling to and from drilling and well sites to help in their operation or respond to problems when they arise.
Employment of petroleum engineers is projected to grow 8 percent over the next ten years, faster than the average for all occupations.
About 1,700 openings for petroleum engineers are projected each year, on average, over the decade. Many of those openings are expected to result from the need to replace workers who transfer to different occupations or exit the labor force, such as to retire.
Some of the projected employment growth in this occupation is due to recovery from the COVID-19 recession of 2020. Demand for petroleum engineers to facilitate oil and gas extraction at existing operations is expected; however, an increase in the use of renewable energy and weaker investment in fossil fuel production may limit job growth over the projections decade.
