Iraq Basrah Heavy crude oil Assay
Basrah Heavy API gravity: 23.6
Anything below 15 API would be considered an extra-heavy crude. Tim FitzgibbonA medium crude is in the 25-35 API range, and a heavy crude is in the 15-25 API range Tim FitzgibbonMore API
Less API
API = (141.5/Specific Gravity) - 131.5
Barrels of Basrah Heavy crude oil per metric ton
In the oil industry, quantities of crude oil are often measured in metric tons. Basrah Heavy 6.89 bbl per MT.
Basrah Heavy Sulfur: 4.2%
Sulfur is considered an undesirable contaminant because, when burned, it generates sulfur oxides.
As a general rule, a crude oil grade with high sulfur content will have a lower value. This type of crude is often referred to as a sour crude.

Basrah Heavy Specific gravity 0.912
Liquids with a density lower than water, which includes most crude oil grades and petroleum products, will have a specific gravity between 0.0 and 1.0.Production of petroleum products from crude oil Basrah Heavy
