What does a drilling engineer do?
A drilling engineer is a specialist at drilling wells.  They will create a plan for drilling different types of wells - vertical and horizontal wells.  They have to have a very good understanding of the subsurface and how temperatures, pressures and depth affect the drilling of a well in real time.  They will also oversee all drilling operations and are involved in completion design, well design and well abandonment.
