Earth is our home and is the source of everything that we require to survive and thrive. Earth gives us food, shelter, and energy. One source of energy, found deep within the earth, is oil. Oil drives the world's economy and is an extremely important commodity. Petroleum engineers spend their careers searching for reservoirs of oil and developing methods to efficiently extract it from the earth without damaging the surrounding environment.Do You Have the Skills and Characteristics of a Petroleum Engineer?

Steps to Get There: Becoming a Petroleum Engineer
High School Subjects to Study
Engineering
Career Pathway Listen to this section
Engineers typically enter the occupation with a bachelor's degree in an engineering specialty, but some basic research positions may require a graduate degree. Continuing education to keep current with rapidly changing technology is important for engineers.
Beginning petroleum engineering graduates usually work under the supervision of experienced engineers and, in large companies, also may receive formal classroom or seminar-type training. As new petroleum engineers gain knowledge and experience, they are assigned more difficult projects with greater independence to develop designs, solve problems, and make decisions. Petroleum engineers may advance to become technical specialists or to supervise a staff or team of engineers and technicians.
Education- Typical Degree Needed After High School Listen to this section
high school credential
Typical degree for an entry-level position: Bachelor's degree ?
A bachelor's degree in petroleum or chemical engineering is required for all entry-level petroleum engineering jobs. Most petroleum engineering programs involve a concentration of study in petroleum engineering, along with courses in both mathematics and the physical and life sciences. Many programs also include courses in general engineering. A design course, sometimes accompanied by a computer or laboratory class, or both, is part of the curriculum of most programs. General courses not directly related to engineering, such as those in the social sciences or humanities, are also often required.
Graduate training is essential for petroleum engineering faculty positions and many research and development programs, but is not required for the majority of entry-level engineering jobs. Many experienced engineers obtain graduate degrees in engineering or business administration to learn new technology and broaden their education. Many high-level executives in government and industry began their careers as engineers.

STEM Activities
STEM activities are fun hands-on explorations that usually take from 10 minutes to one hour and use readily available household or classroom materials while introducing you to STEM concepts common in this career.
Science Project Ideas
Project Ideas are in-depth STEM explorations that have a strong focus on controlling variables, taking accurate measurements, and analyzing data suitable for investigating the scientific method or the engineering design process.
On the Job
Role Models
Nature of the Work
Engineers apply the principles of science and mathematics to develop economical solutions to technical problems. Their work is the link between scientific discoveries and the commercial applications that meet societal and consumer needs.
Petroleum engineers search the world for reservoirs containing oil or natural gas. Once these resources are discovered, petroleum engineers work with geologists and other specialists to understand the geologic formation and properties of the rock containing the reservoir, determine the drilling methods to be used, and monitor drilling and production operations. They design equipment and processes to achieve the maximum profitable recovery of oil and gas. Because only a small proportion of oil and gas in a reservoir flows out under natural forces, petroleum engineers develop and use various enhanced recovery methods. These include injecting water, chemicals, gases, or steam into an oil reservoir to force out more of the oil and doing computer-controlled drilling or fracturing to connect a larger area of a reservoir to a single well. Because even the best techniques in use today recover only a portion of the oil and gas in a reservoir, petroleum engineers research and develop technology and methods to increase recovery and lower the cost of drilling and production operations.
Work Environment
Petroleum engineers work in office buildings, laboratories, or industrial plants. Others may spend time outdoors at oil and gas exploration and production sites, where they monitor or direct operations or solve onsite problems. Some engineers travel extensively to plants or work sites here and abroad.
Many engineers work a standard 40-hour week. At times, deadlines or design standards may bring extra pressure to a job, requiring engineers to work longer hours.
