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.

Display logic

The heatmap now starts with a compact set of main reference oils. Additional oils can be added from dropdowns and independently toggled on or off with checkboxes for clearer comparison.

Main benchmark references

A compact benchmark table remains available below the map.
