Formation and Geological Origins Understanding the description of crude oil requires looking back millions of years to the remains of ancient marine microorganisms. Reservoirs and Traps Once formed, crude oil migrates through porous rock until it is trapped by non-porous cap rock.
Crude Oil Description Global Market Benchmarks
In many mature fields, tertiary recovery or enhanced oil recovery (EOR) methods, such as steam injection or chemical flooding, are necessary to extract the maximum amount of hydrocarbons from the subsurface. Canadian Heavy: A dense, viscous crude requiring specialized refining processes.
Furthermore, the presence of sulfur and other impurities necessitates stringent refining processes to meet environmental regulations and reduce pollutants like sulfur dioxide. Over time, these organic materials were buried under layers of sediment, subjected to intense heat and pressure, and transformed into the liquid hydrocarbons we know today.
Crude Oil Description Global Market Benchmarks and Key Properties
Heavier fractions become lubricants and asphalt, while lighter fractions are converted into the fuels that power vehicles and heat homes. Different regions produce distinct grades of oil, creating a global market where benchmarks like Brent Crude and West Texas Intermediate (WTI) set the price for energy worldwide.
