What are oilfields?

Oilfields are areas of land or sea where large quantities of crude oil are found underground. These regions are developed with wells, pipelines, and other infrastructure necessary to extract, process, and transport oil. Oilfields can vary greatly in size and complexity, from small onshore sites to vast offshore operations. Workers in oilfields perform a variety of roles, including drilling, maintenance, engineering, and safety management. Oilfields are crucial to the global energy industry, providing the raw materials for fuels, plastics, and many other products.
