What Does a Petroleum Engineer Do?
Petroleum engineers design drilling and completion programs, optimize well production, and plan reservoir development - the engineering desk that directs the rig crews, roughnecks, and service-company hands in the field.
Skills That Make a Great Petroleum Engineer
- Reservoir and decline analysis
- Drilling and completion design
- Well-control and process safety
- Project economics modeling
- Field operations judgment
How to Become a Petroleum Engineer
1. Earn an ABET-accredited bachelor’s
Petroleum engineering, or mechanical/chemical engineering with an energy focus for more flexibility.
2. Leverage field experience
Rig, completions, or service-company time is a hiring differentiator operators explicitly screen for.
3. Start as a field or operations engineer
Drilling, completions, and production engineering are the entry tracks.
4. Ride the cycle deliberately
Skills transfer to geothermal, carbon storage, and energy consulting when oil hiring cools.
5. Advance
Senior reservoir engineer, drilling superintendent, or asset management.
Why an Online Degree Works for This Career
The rig-floor-to-engineering-office jump is a storied path in oil and gas: operators genuinely value engineers who have thrown chain. The trade-off to weigh is cyclicality - BLS projects slow growth for the occupation, and hiring tracks commodity prices - but the pay when hired is the highest of any engineering discipline.

For petroleum engineers, the credential is: ABET-accredited bachelor’s in petroleum, mechanical, or chemical engineering. A bachelor’s degree is typically 120 credit hours: four years full-time, and commonly five to six years part-time while working. Transfer credit is the other lever: prior college, military training, apprenticeship coursework, and industry certifications can be worth a year or more at transfer-friendly schools, so get a written transfer evaluation before enrolling anywhere. Costs vary widely by school type; in-state public online programs are usually the value benchmark, and employer tuition assistance is common for working adults in this field.
