Transformation Kerogen converts into hydrocarbons. This specific temperature range, generally between 60°C and 120°C, is known as the "oil window.
The Critical Role of Anoxic Conditions in Oil Formation
The intense heat "cooks" the organic material, converting the solid kerogen into liquid and gaseous hydrocarbons. This combination acts as a catalyst for chemical transformation.
Anoxic Environments and Preservation For organic material to contribute to oil formation, the setting is critical. This geological barrier, known as a trap, acts like a lid, preventing the oil from rising further and collecting it in a reservoir rock where it can accumulate over millions of years.
The Critical Role of Anoxic Conditions in Oil Formation
Increasing pressure, absence of oxygen. Burial Organic matter is covered by layers of sediment.
