In the context of mining and oil drilling, casing refers to a large pipe that is inserted into a well's borehole and then cemented into place. Casings serve various purposes including providing a strong foundation for drilling deeper into the reservoir, preventing water contamination, and containing high pressure oil zones so that blowouts do not reach the surface.
