Once brought to the surface, crude oil is refined into fuels, plastics, and countless other products. Ancient Organic Material: The Starting Point The story of crude oil begins with the life and death of tiny marine organisms.
The Formation of Oil Reservoirs Over Time
Over time, layers of mud and sand covered this organic debris, creating an oxygen-poor environment that prevented complete decay. The weight of overlying rock created intense pressure, compacting the sediments and transforming them into source rocks.
This slow burial process trapped the organic material, setting the stage for the chemical changes that would eventually produce how are crude oil formed. However, it rarely reaches the surface.
How Oil Reservoirs Develop Over Geological Timeframes
Migration and Trapping: How Oil Moves Underground Once formed, the newly created crude oil is not static; it is mobile. Reservoir rocks, like sandstone or limestone, provide the porous space to store the oil.
