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 33,700 jobs. The largest employers of petroleum engineers are as follows:
|Oil and gas extraction||36%|
|Support activities for mining||14|
|Management of companies and enterprises||13|
|Petroleum and coal products manufacturing||10|
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. However, about 1 in 3 work more than 40 hours a week. Overtime may be necessary when traveling to and from drilling sites to help in their operation or respond to problems when they arise.
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.
