What is Petroleum Engineering?
Petroleum Engineering is related to the innovation and exploration of the process of oil and gas extraction. It is advanced from Mining Engineering and Geology, and linked to Geoscience.
The activities in Petroleum Engineering involves development of equipment to extract oil and gas, making plans to drill in oil and gas fields; developing ways to inject water, chemicals, gases, or steam into an oil reserve; keep an eye at oilfield equipment installation, operation and maintenance.
There are many petroleum companies operating worldwide, which creates a better opportunity for Petroleum Engineers. These engineers develop new technology for the production of hydrocarbons from oil shale and offshore oil and gas fields.
The combined efforts of geologists and petroleum engineers throughout the life of a hydrocarbon accumulation determine the way in which a reservoir is developed and depleted, and usually they have the highest impact on field economics. Petroleum engineering requires a good knowledge of many other related disciplines, such as geophysics, petroleum geology, formation evaluation (well logging), drilling, economics, reservoir simulation, reservoir engineering, well engineering, artificial lift systems, completions and petroleum production engineering.
Recruitment to the industry has historically been from the disciplines of physics, mechanical engineering, chemical engineering and mining engineering. Subsequent development training has usually been done within oil companies.
