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. Oil companies often conduct surveys to find the best locations for drilling, and they must also consider environmental impacts. Proper safety measures are essential to protect workers and the surrounding ecosystem during the drilling process.
