The Geology of Hydrocarbon Seepages

Hydrocarbon seepages occur when natural oil and gas slowly escape from Earth's subsurface layers through faults or porous rocks, reaching the surface. These seepages form distinct surface features like tar pools or gas vents. Geologically, they happen in regions with underground source rocks rich in hydrocarbons, often near tectonic activity or sedimentary basins. The seepage process provides valuable clues about underground geology and potential oil or gas reservoirs. Their study helps scientists understand subsurface conditions, migration pathways of hydrocarbons, and locate areas for energy exploration, all while illustrating the dynamic nature of our planet's geology.
