Angola Girassol crude oil Assay
Girassol API gravity: 31
Anything below 15 API would be considered an extra-heavy crude. Tim FitzgibbonMore API

API = (141.5/Specific Gravity) - 131.5
Barrels of Girassol crude oil per metric ton
In the oil industry, quantities of crude oil are often measured in metric tons. Girassol 7.22 bbl per MT.
Girassol Sulfur: 0.33%
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.

Girassol Specific gravity 0.871
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 Girassol
