Oil and gas engineering is an engineering field that studies the theory and technology of oil and gas exploration, evaluation, exploitation, oil and gas separation and transportation. Its master's degree in engineering authorizes the unit to train senior scientific and technological talents engaged in oil and gas generation environment, exploration, oil and gas field exploitation, oil and gas storage and transportation and engineering management. Applying for this major requires not only hard work, but also talent in this field. Therefore, the postgraduate entrance examination for this major is more difficult.
