Directional drilling is a technique used in the oil and gas industry to drill wells at various angles rather than just straight down. This method allows drillers to reach resources that are located far from the drilling site or beneath obstacles like buildings or bodies of water. By using specialized equipment, operators can control the direction of the drill bit, making it possible to access multiple reservoirs from a single location. This technology is also applied in other fields, such as geothermal energy and mining. It helps minimize environmental impact by reducing the number of drilling sites needed. Additionally, directional drilling can improve efficiency and reduce costs by allowing access to hard-to-reach areas.
