Oil seeps are natural occurrences where crude oil escapes from underground reservoirs to the Earth's surface. This can happen through cracks in rocks or soil, allowing the oil to flow out and sometimes form small pools. Oil seeps can be found in various locations around the world, often in areas with significant geological formations. These seeps can have environmental impacts, as the oil can contaminate soil and water. Additionally, they can provide valuable information for geologists studying petroleum formation and migration. Some oil seeps have been historically important, leading to the discovery of larger oil fields nearby.
