Burial and Sedimentation Over millennia, the accumulation of sediments such as sand and clay piled on top of the organic-rich layer. Outside this window, the energy resource is either too heavy or has been destroyed.
Understanding Kerogen Molecule Structure in Oil Formation
The large kerogen molecules are broken down into smaller, lighter hydrocarbon chains. During diagenesis, the buried organic matter breaks down into a waxy substance called kerogen.
When the oil reaches a structural trap, such as an anticline or a fault line, it accumulates, forming the reservoirs that drillers target. It breaks down further into natural gas or, eventually, into elemental carbon and graphite.
Understanding Kerogen Molecule Structure During Oil Formation
Catagenesis: The Birth of Oil Continuing the descent into the Earth’s crust, temperatures climb into the range of 60°C to 120°C. Maturation and the Window of Production Not all organic material becomes oil; the depth and duration of burial dictate the final product.
