The real life alchemists of the 21st century.
Drilling engineering is an important field within petroleum engineering. Drilling deep underground is a key part of the oil extraction process and drilling engineers are focused on safe drilling procedures and the logistics of this process. Drilling engineers usually work closely with geologists to identify potential hazards. This information is then used to determine the most effective drilling equipment, technique and plan. Other tasks include injection well development, where the aim is to increase the ease with which oil can be extracted from a reservoir.
A drilling engineer will spend the majority of his time on site, which can involve extended periods of travel to the remote locations where oil is located.
