Global crude grade atlas

World crude grades and export streams

A trading-oriented directory of named crude streams, benchmark families and export grades used by refiners, traders and analysts.

World crude grades and export streams

World crude grades and export streams

There is no single timeless official list of world crude grades. Names can refer to fields, export blends, terminal streams, benchmark baskets or periodically re-specified commercial families.

For commercial work, what matters is not only the country of origin. Professionals compare density, sulfur, residue behaviour, metals, acidity, logistics, benchmark linkage and how substitutable a barrel is inside a refinery slate.

This atlas therefore groups grades by trading region and follows the grades that are most visible in public assay libraries, benchmark methodology guides and export market practice.

Use the directory below as a commercial map, not as a claim that every cargo in the world is chemically identical from month to month.

How to read crude grades

A crude name is a commercial shorthand

A grade name can point to a field, a blend, a terminal stream or a benchmark family. Traders therefore ask which exact stream, loading point and contract definition is meant.

Quality is multi-dimensional

API gravity and sulfur matter, but so do residue behaviour, metals, acidity, wax, salt, TAN, heating needs and unit constraints inside the refinery.

Price is regional, not universal

A barrel can price off Dated Brent, Dubai/Oman, Murban, WTI/Cushing or local netback structures. Freight and destination optionality often matter as much as lab quality.

Substitution drives market value

Refiners and traders compare how easily one grade can replace another in a crude slate without upsetting yield, sulfur, hydrogen or residue balances.
