API gravity

API gravity reflects crude density relative to water. Higher API values usually indicate lighter oils with stronger yields of gasoline and middle distillates, while lower values trend toward heavier fractions and more complex refining needs.

Sulfur content

Sulfur content is a key quality indicator for crude valuation. Lower sulfur usually means easier refining, lower desulfurisation demand, and reduced environmental treatment burden compared with sourer grades.

Why this map matters

This visual helps compare your stream against well-known market references, making it useful for technical training, classroom explanation, benchmarking exercises, and simplified commercial-quality discussions.
