Within a range typically between 60°C and 120°C (140°F and 250°F), a critical process called catagenesis occurred. It requires a geological trap to accumulate.
How Was Oil Formed Energy History: The Transformation of Ancient Organisms into Crude Oil
This rock must have sufficient porosity to store the oil and permeability to allow it to flow. When these organisms died, their remains sank to the ocean floor, mixing with sediments like mud and silt.
The journey of oil from microscopic marine organisms to the refined fuel powering our world is a story spanning millions of years. This constant rain of organic matter created a nutrient-rich sludge that accumulated over time.
How Was Oil Formed Energy History: From Ancient Organisms to Crude Oil
Modern extraction involves sophisticated drilling techniques to penetrate kilometers of earth and rock to reach these ancient reservoirs. The kerogen molecules began to crack and fracture, reorganizing into the liquid hydrocarbons that define crude oil and natural gas.
