The American Petroleum Institute's "API gravity" is a standard to express the specific weight of oils, computed as (141.5/sp g) - 131.5, where sp is the specific gravity of the oil at 60 degrees ...

In June 2023, production of crude oil with an API gravity between 30.1 and 40.0 degrees reached 2.58 million barrels per day (bpd), exceeding the Texas production of crude oil with a gravity ...

API gravity is a measure of how light or heavy crude is compared to water. Plains pegs condensate as having an API gravity of 45 or higher.
