Petroleum engineering is a branch of engineering that focuses on the exploration, extraction, and production of oil and natural gas. Engineers in this field work to develop methods for locating and extracting these resources efficiently and safely. They analyze geological formations and design drilling plans to maximize production while minimizing environmental impact. The work of petroleum engineers involves collaboration with geologists, geophysicists, and other specialists to assess potential drilling sites. They also oversee the operation of drilling rigs and ensure that safety regulations are followed. Overall, petroleum engineering plays a crucial role in meeting the world's energy needs.
