The specific geological history of a region determines whether these conditions aligned perfectly to create a discoverable oil field. Under specific conditions of temperature and pressure, the complex organic molecules broke down and recombined, forming a waxy substance called kerogen.
How Ancient Sea Life Died and Transformed Into Oil
This immense pressure and the natural geothermal heat from the Earth's core began to transform the buried organic material. The Organic Origins: Life and Death in Ancient Seas The foundation of oil begins with the prolific life forms that thrived in warm, shallow oceans millions of years ago.
Today, the industry has advanced significantly beyond collecting surface seepages. Migration and Trapping: Finding a Home Once generated, the oil is not static.
Ancient Sea Life: The Birth of Oil Under Pressure
Due to its lower density compared to the surrounding rock, it becomes buoyant and begins to migrate upward through porous rock formations. However, oil is rarely found in underground pools.
