Drilling Engineering and Well Completions is a specialized field focused on the design, execution, and preparation of wells to access subsurface resources such as oil, gas, water, or geothermal energy. Drilling engineering encompasses the entire process of creating a borehole, from planning the well trajectory and selecting drilling equipment to managing downhole pressures and ensuring wellbore stability. Once the target depth is reached, well completions takes over, involving the installation of casing and tubing, cementing operations to isolate geological zones, and perforating the well to establish a flow path from the reservoir to the surface, ultimately making the well ready for safe and efficient production or injection.
