Texas accounted for 57% of the total production of crude oil with an API gravity between 30.1 and 40.0 degrees in the Lower 48 states. The administration expects total U.S. crude oil production to ...

The gravity of the crude oil has increased to 48.2° API (Cargo B) from 42.6° API (Cargo A), a difference of 5.6° API. The increase in crude price is $0.17/bbl.

World oil reserves were sorted by API gravity and depth. The gravity classifications are: light (>35°), medium (26-35°), heavy (10°- 26°) and extraheavy (≤10°).
