karwan_y_salih Natural Oil Seeps: Surface Indicators of Subsurface Hydrocarbon Systems: Natural oil seeps are surface expressions of subsurface petroleum systems. They occur when hydrocarbons generated in source rocks migrate upward through geological pathways and reach the Earth's surface, forming visible accumulations of crude oil, tar, or gas emissions. These phenomena provide valuable geological and geochemical information about active hydrocarbon generation and migration processes. Formatio
