Hydraulic drilling is a technique that uses high-pressure fluid to create holes in the ground. This method is commonly employed in the extraction of natural resources, such as oil and gas, as well as in construction projects. The fluid, often a mixture of water and additives, helps to cool the drill bit and remove debris from the hole. The process involves pumping the fluid through a drill pipe to the drill bit, where it is forced out under pressure. This not only facilitates drilling but also stabilizes the hole and prevents collapse. Hydraulic drilling is efficient and can reach great depths, making it a valuable tool in various industries.
