It must be refined to separate useful products like gasoline, diesel, and jet fuel. When these creatures died, their remains settled on the seabed, mixing with sediment and becoming part of a nutrient-rich muck.
The raw material extracted from the ground is a complex mixture of hydrocarbons and impurities. This trap, often capped by an impermeable rock layer, is where the oil accumulates into a reservoir.

In environments lacking oxygen—known as anoxic conditions—bacteria were unable to break down the material entirely. Between 60°C and 120°C, a process called catagenesis takes place.
