This combination cooked the organic material, a process known as diagenesis and catagenesis. The versatility of these derivatives is why oil remains a dominant energy source globally.
The Ancient Origins of Crude Oil From Earth's Depths
Because it is less dense than water and rock, it migrates upward through porous formations like sandstone. Kerogen, a waxy substance, broke down through chemical transformation, eventually cracking into the liquid hydrocarbons that migrated through porous rock.
Humans locate these deposits using seismic surveys and geological mapping. When these creatures died, they sank to the sea floor, mixing with sediments and algae.
From Ancient Organic Material to Crude Oil Formation
Crude oil is a fossil fuel formed from the compressed remains of microscopic organisms and plants that lived long before humans walked the Earth. As the world transitions toward sustainable energy, the legacy of oil continues to shape economies and geopolitics, even as society seeks cleaner alternatives for the future.
