Petroleum engineering (also called oil and gas engineering) is the application of engineering principles to the production of oil, natural gas, and other hydrocarbon products. It focuses on maximizing the economic recovery of these hydrocarbons by drawing upon a detailed understanding of the physical behavior of oil, water, and gas within rock at very high pressure.
Petroleum engineering is generally subdivided into 3 fields. Reservoir engineering is the optimization of the production of oil and gas via proper well placement and the enhancement of oil recovery techniques. Drilling engineering focuses on drilling wells. Production engineering manages the interface between reservoir and well, including sand control, downhole flow control, and evaluating artificial lift methods.
About Petroleum Engineering
Petroleum engineering is similar to geology, chemical engineering, and geophysics. Some schools group chemical and petroleum engineering into the same department.
