As more sediment accumulated, the organic matter was compressed and began to change chemically. Further Conversion to Crude Oil With increased depth and temperature, kerogen underwent thermal cracking, transforming into liquid hydrocarbons.
Crude Oil Migration and the Formation of Reservoir Traps
Sedimentation: The Burial Process Over millions of years, layers of sediment accumulated on top of the organic matter, burying it deeper beneath the Earth's surface. This continuous burial process isolated the organic material from oxygen, preventing complete decomposition.
Extraction and Modern Recovery Once trapped, crude oil is extracted using drilling techniques. The Biological Origins: Ancient Plankton and Algae The story of crude oil begins in ancient oceans, lakes, and seas where microscopic organisms such as algae and plankton thrived.
How Crude Oil Forms and Migrates to Create Reservoir Traps
The hydrocarbons migrated through porous rock formations, eventually accumulating in reservoir rocks where they formed oil pools. Heat and Pressure Transformation Deep underground, the buried organic matter was subjected to high temperatures and pressures.
More About How crude oil was made
Looking at How crude oil was made from another angle can help expand the discussion and give readers a second clear paragraph under the same section.
