This chemical process broke down the large, complex organic molecules into smaller, liquid hydrocarbon chains, effectively generating crude oil and natural gas. Migration and Trapping Once formed, the newly created oil is not stationary.
From Kerogen to Crude: How Organic Matter Transforms into Oil and Natural Gas
Burial and Transformation Under Heat and Pressure Over time, layers of sediment accumulated on top of the organic sludge, burying it deeper beneath the Earth's surface. Due to its lower density compared to surrounding water and rock, it becomes buoyant and begins to migrate upward through porous rock layers.
Composition and Variability No two oil deposits are identical, as the specific composition depends on the original biological source and the geological history it endured. This critical window of temperature and time is known as the oil window.
Kerogen Cracking: How Organic Matter Transforms into Oil and Natural Gas
The Organic Origins: Plankton and Algae The primary ingredients for oil are the tiny remains of marine plankton, including algae and zooplankton, that thrived in ancient seas. The source rock, rich in the initial organic material, must be heated to the correct temperature.
