Primary recovery relies on natural pressure, while secondary recovery involves injecting water or gas to push more oil to the surface. These geological structures, such as anticlines, fault traps, and salt domes, act as reservoirs that hold the oil in place until extraction.
Understanding Geological Traps and Migration Pathways for Crude Oil
As more sediment accumulated, the organic matter was compressed and began to change chemically. Enhanced oil recovery methods, such as thermal injection and chemical flooding, are used to extract remaining reserves efficiently.
Crude oil is a fossil fuel formed from the remains of tiny aquatic organisms called plankton that lived millions of years ago. 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.

This stage, known as catagenesis, occurred at temperatures between 90°C to 160°C (194°F to 320°F). When these organisms died, their remains settled on the seabed, mixing with mud and silt.
