Drill rigs are large machines used to create holes in the ground for various purposes, such as oil and gas exploration, mining, and construction. They can be mobile or stationary and come in different types, including rotary, percussion, and auger rigs. Each type is designed for specific drilling conditions and depths. These rigs operate by using a drill bit to penetrate the earth's surface, often with the help of drilling fluids to cool the bit and remove debris. The information gathered from drilling can help locate resources like oil, natural gas, and minerals, making drill rigs essential in resource extraction industries.
