Oil is a natural resource found beneath the surface of the Interior Plains.

The Interior Plains are rich in oil reserves, making this region a significant contributor to North America's energy production. Extensive geological formations, such as sedimentary basins, contain large deposits of crude oil, which are extracted through drilling. This natural resource plays a crucial role in the local economy, providing jobs and revenue while fueling industries and transportation. However, oil extraction also raises environmental concerns, including habitat disruption, pollution, and greenhouse gas emissions. As a result, balancing economic benefits with environmental protection is essential for the sustainable management of oil resources in the Interior Plains.
