Crude oil, the black gold driving modern civilization, originates from the ancient remains of microscopic marine organisms. This burial created an isolated environment where the organic material, known as kerogen, could be preserved instead of being recycled back into the ecosystem.

However, it doesn't travel freely. Typically, temperatures between 60°C and 120°C (140°F to 250°F) at depths of 1.
Over thousands to millions of years, the increasing weight of overlying sediments generated intense pressure and heat. Oxygen-poor (anoxic) conditions on the sea floor were crucial, preventing bacteria from fully breaking down the material.

Catagenesis: Takes place at greater depths and temperatures (60–120°C), where kerogen "cracks" into liquid petroleum. Variations in Crude Oil: The Geological Signature Not all crude oil is the same.
