Petroleum Engineering Major
Petroleum Engineering is the study of how to locate and produce oil and natural gas. It is a major within Engineering & Technology.
Petroleum engineering is the study of how to find, extract, and produce oil and natural gas from underground reservoirs. Students learn the science and math needed to understand rock formations, fluid flow, and pressure conditions deep below the surface. The field focuses on practical questions: How do you drill safely and efficiently? How do you maximize the amount of resource recovered from a deposit? How do you manage the technical and environmental challenges that come with extraction? The work combines geology, physics, chemistry, and problem-solving with real-world constraints like cost, safety, and operational feasibility.
Students drawn to this major typically have strong interests in math and science, curiosity about how natural resources are obtained, and an aptitude for solving complex technical problems. The curriculum usually begins with foundational courses in mathematics, chemistry, physics, and geology. As students progress, they move into more specialized topics in reservoir analysis, drilling engineering, and production systems. Coursework typically mixes classroom instruction with lab work and field projects that let students apply concepts to realistic scenarios. This progression from general scientific principles to field-specific applications helps students develop both the theoretical knowledge and practical understanding needed for the work.
Typical coursework
Course requirements vary by school, but a Petroleum Engineering program commonly includes topics such as:
- Reservoir engineering
- Drilling engineering
- Production engineering
- Petrophysics
- Geology
- Thermodynamics
Most programs also include general-education requirements and, in many fields, a capstone project, internship, or research experience.
Degree levels
Petroleum Engineering is commonly offered at these levels:
- Bachelor's
- Master's
- Doctoral
Availability differs by institution, and program names can vary (for example, a Bachelor of Arts versus a Bachelor of Science track).
Common career directions
Graduates with a Petroleum Engineering background pursue a range of paths. Some roles related to this field of study include:
- Petroleum engineer
- Reservoir engineer
- Drilling engineer
- Production engineer
Many careers require additional steps beyond the major — such as a graduate degree, a license, or a certification — and many graduates work in fields unrelated to their major. What you study is one factor among many in where your career goes.
