Oil rigs are large structures used to extract oil and natural gas from beneath the Earth's surface. They can be found on land or offshore in oceans and seas. These rigs are equipped with drilling equipment that reaches deep into the ground to access valuable resources. Workers on oil rigs play a crucial role in ensuring the extraction process is safe and efficient. Offshore oil rigs are often massive platforms that float on water, supported by strong pillars. They are designed to withstand harsh weather conditions and can be quite complex, featuring living quarters, control rooms, and machinery. The extracted oil is then transported to refineries for processing into fuels and other products.
