Oil and gas fields are areas where natural deposits of oil and natural gas are found beneath the Earth's surface. These fields are typically located in sedimentary rock formations, where organic materials have been buried and transformed over millions of years. The extraction of these resources is essential for energy production and various industrial processes. To access the oil and gas, companies drill wells into the ground, allowing the resources to flow to the surface. Once extracted, the oil and gas can be refined and processed for use in fuels, plastics, and other products. Proper management of these fields is crucial for environmental sustainability and energy security.
