Overview
The profession got its start in 1914 within the
American Institute of Mining, Metallurgical and Petroleum Engineers (AIME). The first Petroleum Engineering degree was conferred in 1915 by the
University of Pittsburgh
The University of Pittsburgh (Pitt) is a Commonwealth System of Higher Education, state-related research university in Pittsburgh, Pennsylvania, United States. The university is composed of seventeen undergraduate and graduate schools and colle ...
. Since then, the profession has evolved to solve increasingly difficult situations. Improvements in computer modeling, materials and the application of statistics, probability analysis, and new technologies like
horizontal drilling and
enhanced oil recovery
Enhanced oil recovery (abbreviated EOR), also called tertiary recovery, is the extraction of crude oil from an oil field that cannot be extracted after primary and secondary recovery methods have been completely exhausted. Whereas primary and se ...
, have drastically improved the toolbox of the petroleum engineer in recent decades. Automation, sensors, and robots are being used to propel the industry to more efficiency and safety.
Deep-water, arctic and desert conditions are usually contended with. High temperature and high pressure (HTHP) environments have become increasingly commonplace in operations and require the petroleum engineer to be savvy in topics as wide-ranging as thermo-hydraulics, geomechanics, and intelligent systems.

It provides free online education (webinars), mentoring, and access to SPE Connect, an exclusive platform for members to discuss technical issues, best practices, and other topics. SPE members also are able to access the SPE Competency Management Tool to find knowledge and skill strengths and opportunities for growth. SPE publishes peer-reviewed journals, books, and magazines. SPE members receive a complimentary subscription to the ''Journal of Petroleum Technology'' and discounts on SPE's other publications.
SPE members also receive discounts on registration fees for SPE organized events and training courses.
SPE provides scholarships and fellowships to undergraduate and graduate students.
According to the United States Department of Labor's Bureau of Labor Statistics, petroleum engineers are required to have a bachelor's degree in engineering, generally a degree focused on petroleum engineering is preferred, but degrees in mechanical, chemical, and civil engineering are satisfactory as well.
Petroleum engineering education is available at many universities in the
United States

and throughout the world - primarily in oil producing regions. ''U.S. News & World Report'' maintains a list of the Best Undergraduate Petroleum Engineering Programs. SPE and some private companies offer training courses. Some oil companies have considerable in-house petroleum engineering training classes.
Petroleum engineering salaries
Petroleum engineering has historically been one of the highest-paid engineering disciplines, although there is a tendency for mass layoffs when oil prices decline and waves of hiring as prices rise. In 2020, the United States Department of Labor's Bureau of Labor Statistics reported the median pay for petroleum engineers was US$137,330, or roughly $66.02 per hour.
The same summary projects there will be 3% job growth in this field from 2019 to 2029.
SPE annually conducts a
salary survey. In 2017, SPE reported that the average SPE professional member reported earning US$194,649 (including salary and bonus).
The average base pay reported in 2016 was $143,006.
Base pay and other compensation was on average was highest in the United States where the base pay was US$174,283. Drilling and production engineers tended to make the best base pay, US$160,026 for drilling engineers and US$158,964 for production engineers. Average base pay ranged from US$96,382-174,283.
There are still significant gender pay gaps, plus or minus 5% of the US average pay gap which was 18% difference in 2017.
Also in 2016, ''U.S. News & World Report'' named petroleum engineering the top college major in terms of highest median annual wages of college-educated workers (age 25–59). The 2010 National Association of Colleges and Employers survey showed petroleum engineers as the highest paid 2010 graduates, at an average annual salary of $125,220. For individuals with experience, salaries can range from $170,000 to $260,000. They make an average of $112,000 a year and about $53.75 per hour. In a 2007 article, Forbes.com reported that petroleum engineering was the 24th best paying job in the United States.
Sub-disciplines
Petroleum engineers divide themselves into several types:
*
Reservoir engineers work to optimize production of oil and gas via proper placement, production rates, and enhanced oil recovery techniques.
*
Drilling engineers manage the technical aspects of drilling exploratory, production and injection wells.
*
Drilling fluid engineers A mud engineer (correctly called a Drilling Fluids Engineer, but most often referred to as the "Mud Man") works on an oil well or gas well drilling rig, and is responsible ensuring the properties of the drilling fluid, also known as drilling mud, are within designed specifications.
*
Completion engineers (also known as subsurface engineers) work to design and oversee the implementation of techniques aimed at ensuring wells are drilled stably and with the maximum opportunity for oil and gas production.
*
Production engineers manage the interface between the reservoir and the well, including perforations, sand control, downhole flow control, and downhole monitoring equipment; evaluate
artificial lift methods; and select surface equipment that separates the produced fluids (oil, natural gas, and water).
*
Petrophysicists gather information about subsurface properties to build wellbore stability models and study rock properties

roller cone, fixed cutter, and hybrid, each use teeth to break up the rock. To optimize drilling efficiency and cost, drilling engineers make use of drilling simulators that allow them to identify drilling conditions.
Drilling technologies including horizontal drilling and
directional drilling have been developed to obtain hydrocarbons profitably from
impermeable and
coal-bed methane accumulations.
