What is an oil rig?

Oil rigs are large structures or platforms used to extract oil and natural gas from beneath the Earth's surface, typically from beneath the ocean floor or underground reservoirs. They house equipment, machinery, and personnel necessary for drilling, extracting, and sometimes processing oil and gas. Oil rigs can be either onshore (located on land) or offshore (located at sea), with offshore rigs often being massive engineering feats. Working on oil rigs can involve challenging conditions, but these structures are essential to the global energy industry. There are various types of oil rigs, including drillships, jack-up rigs, and semi-submersible platforms.
