The Final Product: Refining Ancient Sunlight After being brought to the surface, the raw crude oil is far from the gasoline or jet fuel we use. Enhanced recovery methods, such as injecting water or gas, are often used to maximize the amount of oil that can be economically extracted from a single field.

Modern extraction involves sophisticated drilling techniques to penetrate kilometers of earth and rock to reach these ancient reservoirs. The Transformation: From Kerogen to Crude Burial and Heat Over millennia, layers of sediment accumulated on top of the organic-rich ooze, burying it deeper and deeper.
When these organisms died, their remains sank to the ocean floor, mixing with sediments like mud and silt. However, oil is rarely found in underground pools.

This fractional distillation process breaks the ancient biomass down again, yielding not only transportation fuels but also the thousands of other petroleum products that form the backbone of modern industry and manufacturing. The caprock, often a dense shale or salt formation, is the essential seal that creates the reservoir trap.
