This constant rain of organic matter created a nutrient-rich sludge that accumulated over time. Under specific conditions of temperature and pressure, the complex organic molecules broke down and recombined, forming a waxy substance called kerogen.
Geological Processes: From Organic Sludge to Crude Oil Formation
This fractional distillation process breaks the ancient biomass down again, yielding not only transportation fuels but also the thousands of other petroleum products that form the backbone of modern industry and manufacturing. The Transformation: From Kerogen to Crude Burial and Heat Over millennia, layers of sediment accumulated on top of the organic-rich ooze, burying it deeper and deeper.
The specific geological history of a region determines whether these conditions aligned perfectly to create a discoverable oil field. Today, the industry has advanced significantly beyond collecting surface seepages.

Here, the different hydrocarbon chains are separated based on their boiling points. Catagenesis: The "Oil Window" As burial continued, temperatures gradually increased.
