These geological traps are where we find the majority of the world's commercially viable oil deposits. This organic material was buried under layers of mud and sand, creating an oxygen-poor environment that prevented complete decay.
The Transformation of Ancient Biomass into Crude Oil
The Role of Heat and Pressure As more sediment accumulated, the organic matter was subjected to increasing heat and pressure. Understanding how is crude oil form requires looking deep underground, where heat and pressure transformed ancient biomass into the liquid hydrocarbon mixture we extract today.
Microscopic plankton, algae, and other organic matter accumulated on the sea floor, mixing with sediments. These differences are a direct result of the specific geological history and conditions present during its formation.
The Transformation of Ancient Biomass into Crude Oil
Transformation into Liquid Hydrocarbons With continued burial and deeper penetration into the Earth's crust, the temperature and pressure rose further. This triggered the process of catagenesis, where kerogen transformed into liquid and gaseous hydrocarbons.
