Petroleum engineering is primarily concerned with the economic extraction of oil, gas, and other natural resources from the earth. Students in this field will learn to design oil wells, storage tanks, and transportation systems. They will also learn how to supervise the construction and operation of oil and gas fields. Petroleum engineers are researching new technologies to allow more oil and gas to be extracted from each well. They keep the energy flowing to light and heat our homes. They fuel our transportation systems and keep our industries operating. Economical and environmentally safe production of petroleum requires a wide spectrum of knowledge. Petroleum engineers also contribute to non-energy concerns such as underground waste disposal, ground water remediation, and hydrology.
