oil wells

An oil well is a drilled hole in the Earth's surface used to extract underground oil deposits. Once drilled, the well taps into underground rock formations where oil accumulates. Through casings and pumping equipment, the oil flows to the surface for processing and use. Drilling involves precise engineering to reach oil reservoirs safely and efficiently. Oil wells can be on land or offshore, and their operation is vital for supplying the energy needed for transportation, heating, and industry. They are part of complex systems that manage extraction, protect the environment, and optimize resource recovery.
