Transformation into Kerogen With continued heat and pressure over millions of years, the organic matter underwent chemical changes, converting into a waxy substance called kerogen. This trapping mechanism creates an oil reservoir, which exploration companies target with drilling operations.
Geological Process of Oil Generation: From Organic Matter to Kerogen
Extraction and Refining Once geologists and engineers identify a reservoir, they drill wells to bring the crude oil to the surface. The oil then begins to migrate from the source rock into more porous reservoir rocks that can hold significant quantities of fluid.
After extraction, the raw crude is transported to refineries, where it is heated and separated into different components like gasoline, diesel, jet fuel, and lubricants. Deposition and Burial As sediments accumulated, the organic-rich layers became buried deeper and deeper under accumulating rock.
Geological Process of Oil Generation and Kerogen Formation
Tiny organisms like algae and zooplankton, along with plants and other organic material, lived, died, and settled on the bottoms of these water bodies. Extracting and burning crude oil releases carbon dioxide and other emissions, which contribute to climate change.
