    This Thesis explores the design and performance of turbo-drills, downhole hydraulic motors that convert drilling fluid energy into mechanical rotation to drive the drill bit. Turbo-drills offer advantages over conventional surface-driven systems, including higher stability, reduced drill string stress, and improved efficiency in deep or complex wells. The work focuses on how variations in blade geometry influence the overall performance of the tool. Using numerical modeling in ANSYS, different blade parameters such as inlet angle, outlet angle, thickness, and number of blades were systematically studied. The results highlight that blade geometry strongly affects torque, power output, with the outlet angle proving to be the most influential factor. The study provides insights into the role of blade design in optimizing turbo-drill efficiency and establishes a methodological framework for future improvements in downhole turbine technology.
