Drilling methods are techniques used to create holes in various materials, primarily for extracting resources like oil, gas, or minerals. Common methods include rotary drilling, where a rotating drill bit cuts through the material, and percussive drilling, which uses repeated blows to break the surface. Each method is chosen based on the type of material and the depth required. Another important method is directional drilling, which allows for drilling at various angles rather than just straight down. This technique is particularly useful in accessing resources located beneath obstacles, such as buildings or bodies of water, making it a valuable tool in modern resource extraction.
