Trap formation, cap rock. Crude oil is a fossil energy source formed from the buried remains of microscopic marine organisms that lived hundreds of millions of years ago.
How Crude Oil Forms Traps and Reservoirs
If the heat is insufficient, the material remains as kerogen or bitumen. Burial, compaction, low temperatures Catagenesis Kerogen breaks down into oil and gas.
" If temperatures exceed this range, the hydrocarbons break down further into natural gas. 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.
How Crude Oil Forms Traps and Reservoirs Beneath the Surface
From Kerogen to Hydrocarbons As more sediment accumulated, the organic-rich layers were subjected to increasing heat and pressure. Migration and Trapping: How Oil Collects Once formed, crude oil is not static.
