Well Engineering is a branch of engineering focused on the design, construction, and maintenance of wells used for extracting natural resources like oil, gas, and water. It involves various processes, including drilling, casing, and completing the well to ensure it operates efficiently and safely. The field combines principles from geology, petroleum engineering, and environmental science to assess the best methods for well development. Engineers must consider factors such as rock formations, fluid dynamics, and environmental impact to optimize resource extraction while minimizing risks to surrounding ecosystems.
