These organisms lived brief lives, multiplying rapidly in nutrient-rich waters before dying and sinking to the sea floor. Light crude, which flows easily and contains fewer impurities, commands higher prices due to its efficiency.
How Is Oil Created Variations Crude: Light, Heavy, and Sulfur Content Differences
Typically, temperatures between 60°C and 120°C (140°F to 250°F) at depths of 1. Oxygen-poor (anoxic) conditions on the sea floor were crucial, preventing bacteria from fully breaking down the material.
The sulfur content also varies, with "sweet" oil containing low sulfur and "sour" oil requiring more refining. Heavy crude is denser and more viscous.
