The organic matter trapped in anaerobic environments—such as ocean basins—does not fully decompose. The extraction, transport, and combustion of these fossil fuels contribute significantly to greenhouse gas emissions, driving research into carbon capture and the transition toward alternative energy sources.

Sulfur content classifies the material as "sweet" (low sulfur) or "sour" (high sulfur), as sulfur compounds require complex removal processes during refining to meet environmental standards and prevent corrosion in equipment. These hydrocarbon chains vary significantly in length and structure, which directly influences the physical properties and refining process for the crude.
The migration of these hydrocarbons through porous rock formations is a critical step, leading to accumulation in reservoir rocks sealed by impermeable cap rock. Once brought to the surface, the raw crude is not yet ready for market; it undergoes initial separation at the wellhead or processing facility to remove water, natural gas, and solid impurities.
