Diagenesis: The Early Transformation As the depth increases, the temperature and pressure rise, initiating the first chemical changes. If the temperature exceeds 120°C for an extended period, the oil continues to degrade.
How Is Oil Formed Recognizing Timeline Value
Outside this window, the energy resource is either too heavy or has been destroyed. From the fall of ancient plankton to the slow dance of molecules under heat and pressure, the process underscores the finite nature of fossil fuels.
Kerogen is a solid, mixture of organic chemical compounds that retains the complex molecular structure of the original biological material without yet becoming liquid oil. The formation of oil is a multi-million year process, requiring specific biological, geological, and thermal conditions to occur.

It encounters cap rocks—dense, non-porous layers like shale or salt—that act as a seal. The critical step here is the isolation of the organic material from oxygen.
