This is the sweet spot where liquid crude oil is generated. Organic Material: The Raw Ingredient The story of oil starts with the constant rain of biological matter into sedimentary basins.
Crude Oil Composition and Refinery Process Explained
A Non-Renewable Resource It is crucial to understand the timescale involved in this process. Here, the large, complex organic molecules break down into smaller, lighter hydrocarbon chains.
This complex process, known as the formation of fossil fuels, specifically creates liquid hydrocarbons we recognize as crude oil over millions of years. However, in environments where oxygen is scarce—such as the deep sea or anoxic lake bottoms—decomposition slows dramatically.
Crude Oil Composition and Refining Process
Once brought to the surface, the crude oil is a complex mixture of various hydrocarbons. This reservoir is then sealed by an impermeable cap rock, such as shale or salt, which prevents the oil from continuing its upward escape.
