Petroleum Engineer Job Descriptions, Average Salary, Interview Questions

What Does a Petroleum Engineer Do?

Oil-based fuels and chemical compounds are vital to the world economy. A petroleum engineer designs the equipment and systems used to extract oil and gas used in the creation of these products. Petroleum engineers design drill equipment for onshore and offshore activities and recommend plans based on the cost, effort involved, and potential return on investment of time and resources. Petroleum engineers also evaluate the production of oil and gas wells through surveys and testing.

Petroleum engineers work with geoscientists and other specialists to understand the rock formations surrounding oil and gas deposits. For this reason, petroleum engineers must possess interpersonal, communication, and teamwork skills. Petroleum engineers must also have advanced research skills, as they are often required to find new ways to extract as much oil and gas as possible from underground reserves.
