If temperatures exceed the oil window and enter the "gas window" above 120°C, the hydrocarbons break down further into natural gas. Organic Material: The Raw Ingredient The story of oil starts with the constant rain of biological matter into sedimentary basins.
How Oil Matures Inside Earth Layers During Diagenesis and Thermal Cracking
Migration and Trapping Once formed, the oil does not remain stationary. When the kerogen reaches the "oil window"—typically between 60°C and 120°C—the thermal cracking process occurs.
Extraction and Refinement Humans intervene in this slow process by drilling wells to access these underground reservoirs. This fundamental disparity defines the challenge of sustainability and underscores why oil is classified as a non-renewable resource, despite its origins in the continuous cycle of life and death on Earth.
How Oil Matures Inside Earth Layers During Diagenesis and Thermal Cracking
Microscopic organisms like algae and zooplankton, along with vast quantities of plant material, accumulate on the floors of oceans, seas, and lakes. This initial transformation phase is called diagenesis.
