Outside this window, the energy resource is either too heavy or has been destroyed. This stage, known as diagenesis, typically occurs at temperatures below 50°C.

This window of heat and pressure triggers catagenesis, the critical phase where kerogen undergoes thermal cracking. The critical step here is the isolation of the organic material from oxygen.
When the oil reaches a structural trap, such as an anticline or a fault line, it accumulates, forming the reservoirs that drillers target. Understanding this journey clarifies why oil is a non-renewable resource and how its extraction reflects the patience of geological time.

It encounters cap rocks—dense, non-porous layers like shale or salt—that act as a seal. Anoxic conditions are essential, as they slow the decay process and allow the complex organic molecules to survive long enough to undergo transformation.
