A drilling rig is a large structure used to create holes in the ground for extracting natural resources like oil and gas. It consists of various components, including a drill bit, derrick, and power systems, which work together to penetrate the earth's surface. The rig can be stationary or mobile, depending on the location and type of drilling operation. Drilling rigs are often found in oil fields or offshore locations, where they help access resources buried deep beneath the ground or seabed. The process involves drilling through layers of rock and soil, and the extracted materials are then transported for processing and refinement.
