With continued burial and deeper penetration into the Earth’s crust, kerogen underwent thermal cracking during the catagenesis stage, breaking down into liquid and gaseous hydrocarbons. Migration and Trapping: How Oil Collects Once formed, crude oil is not static.
The Role of Permeability in Crude Oil Formation and Migration
When these organisms died, their bodies sank to the seabed or lake bottom, mixing with sediments. Under intense heat and pressure deep within the Earth, these organic materials transformed into the liquid hydrocarbons that power modern industry.
Geological Structures That Hold Oil Traps are essential geological features that prevent petroleum from escaping to the surface. Source Rock: Fine-grained sedimentary rocks rich in organic matter, such as shale.
The Role of Permeability in Crude Oil Formation and Migration
From Kerogen to Hydrocarbons As more sediment accumulated, the organic-rich layers were subjected to increasing heat and pressure. Crude oil is a fossil energy source formed from the buried remains of microscopic marine organisms that lived hundreds of millions of years ago.
