Oil drilling is the process of extracting crude oil from beneath the Earth's surface. It involves drilling a hole, called a well, into the ground to reach oil reservoirs. Once the well is drilled, various techniques are used to bring the oil to the surface, where it can be processed and refined into products like gasoline and diesel fuel. The equipment used in oil drilling includes large drilling rigs and specialized tools. Workers, often referred to as oilfield workers, operate this equipment and ensure the drilling process is safe and efficient. Oil drilling plays a crucial role in the global economy, providing energy for transportation and industry.
