well drilling techniques

Well drilling techniques involve creating a hole in the earth to access underground resources like water, oil, or natural gas. The most common method is rotary drilling, where a drill bit attached to a rotating drill pipe cuts into the ground, while drilling fluid (mud) circulates to cool the bit, remove debris, and stabilize the well. Other methods include cable tool drilling, which uses a repetitive hammering motion. Techniques vary based on depth, geology, and resource type, and specialized equipment ensures safe, efficient, and precise well construction.
