Stage Description Key Conditions Diagenesis Organic matter converts to kerogen. " If temperatures exceed this range, the hydrocarbons break down further into natural gas.
How Is Crude Oil Formed Under Sea: The Subaquatic Journey of Hydrocarbon Creation
The Organic Origins: Building Blocks of Crude Oil The story of crude oil begins in ancient seas, lagoons, and lakes where plankton, algae, and other microorganisms flourished. Anticlines, where rock layers arch upward, are classic traps.
Under intense heat and pressure deep within the Earth, these organic materials transformed into the liquid hydrocarbons that power modern industry. Heat (60-120°C), pressure, time Migration Oil moves through rock pores.
How Is Crude Oil Formed Under Sea: The Subaquatic Journey
Unlike material on the surface that decomposes completely, these remains were buried quickly by layers of mud and silt, protecting them from oxygen and allowing them to accumulate over time. When these organisms died, their bodies sank to the seabed or lake bottom, mixing with sediments.
