Over geological time scales, the kerogen molecules begin to break down in a process called diagenesis. Heat, Pressure, and Transformation As more sediment piles on top, the organic-rich layer is buried deeper.
The Process of Oil Reservoir Formation
Heat (60-120°C), pressure, time. It starts with the accumulation of organic matter, primarily the remains of tiny marine organisms like plankton and algae.
Accumulation Oil pools in a reservoir rock. In environments lacking sufficient oxygen, this organic debris avoids complete decomposition.
The Process of Oil Reservoir Formation
Organic Material: The Starting Ingredient The journey of oil begins long before rock layers can trap it. High oxygen levels would result in the material being consumed entirely, leaving only trace amounts of carbon.
