When the oil reaches a structural trap, such as an anticline or a fault line, it accumulates, forming the reservoirs that drillers target. Catagenesis: The Birth of Oil Continuing the descent into the Earth’s crust, temperatures climb into the range of 60°C to 120°C.
Understanding Catagenesis: The Transformation of Kerogen into Oil
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. When these creatures died, their bodies sank to the seafloor, mixing with sediments and mud.
This constant burial subjected the material to significant pressure, compressing the sediments into rock. Driven by pressure, it begins to migrate upward through porous rock formations.

The critical step here is the isolation of the organic material from oxygen. It breaks down further into natural gas or, eventually, into elemental carbon and graphite.
