Frequently Asked Questions

Does EIA have data on the type or quality of crude oil?

The U.S. Energy Information Administration (EIA) publishes the monthly and annual average sulfur content and API gravity of all crude oil input to U.S. refineries by Petroleum Administration for Defense District (PADD) and refining district.

EIA also publishes the sulfur content and API gravity of imported crude oil, along with the volume, source country, and name of the processing facility (refinery) that received the oil, in the Company Level Imports data file. Columns M and N in this data file have the sulfur and API gravity data.

EIA has an analysis of the quality of crude oils produced in different regions of the United States in U.S. Crude Oil Production to 2025: Updated Projection of Crude Types.
