Over time, more layers accumulated, creating immense pressure on the deeper deposits. The lipids in the cell walls of these ancient plankton are molecularly similar to the components of crude oil.
Sedimentary Basin Stores Crude Oil
When the oil reaches this impermeable cap, often made of rock like shale or salt, it pools, forming a reservoir. Migration and Trapping: Finding the Reservoir After the oil formed, it did not remain in the source rock.
These included algae—plant-like cells that perform photosynthesis—and zooplankton—tiny animals that fed on the algae. The primary contributors to oil formation were not large dinosaurs, as often depicted, but rather immense quantities of microscopic organisms.

If the temperature exceeded this window, the material would break down further into natural gas. Extraction: Bringing the Oil to the Surface With the reservoir identified, the modern industry turns to extraction.
