Once the oil is generated, it does not remain stationary. Unlike material that decomposes on the surface, this organic matter was buried quickly under layers of mud and silt.
From Organic Source Rock to Crude: The Formation Journey
However, the earth’s geology acts like a filter. When this pressure declines, secondary recovery techniques like water injection are used to maintain flow.
Extraction and Modern Recovery After millions of years of formation, the oil is extracted using modern technology. Here, the increasing weight created intense pressure, while the Earth’s internal heat raised the temperature.

Transformation Through Heat and Pressure As newer sediments piled on top, the organic-rich layer was pushed deeper underground. Primary recovery relies on the natural pressure of the reservoir to push oil to the surface.
