Transformation Under Pressure: The Role of Heat and Time Burial depth is critical, as it determines temperature and pressure. It encounters geological barriers—such as impermeable cap rock, faults, or folds—that trap it in underground reservoirs.

Light crude, which flows easily and contains fewer impurities, commands higher prices due to its efficiency. Along with marine sediments and occasional plankton blooms, they accumulated in thick layers of organic sludge, creating a concentrated soup of carbon-rich material that would eventually become the foundation of fossil fuels.
Metagenesis: The final stage at even higher temperatures, which can convert oil into natural gas. This burial created an isolated environment where the organic material, known as kerogen, could be preserved instead of being recycled back into the ecosystem.

The Organic Origins: Life and Death in Ancient Seas The story of oil begins millions of years ago, primarily in warm, shallow seas that once covered vast regions of the Earth. Typically, temperatures between 60°C and 120°C (140°F to 250°F) at depths of 1.
