A well{3} from which petroleum is or has been extracted; a well{3} drilled deeply into an oil-bearing geological formation specifically for the purpose of obtaining petroleum.
An oil well is a term for any perforation through the Earth's surface designed to find and release both petroleum oil and gas hydrocarbons. The well is created by drilling a hole (5 to 30 inches wide) into the earth with an oil rig turning a drill bit. After the hole is drilled, a metal pipe is cemented into the hole. In order to get access to the hydrocarbon producing interval, the pipe and cement are either perforated or additional sections of earth are drilled below the casing.
