Norway Ekofisk crude oil Assay
Ekofisk API gravity: 37.5
Light crude is typically in the 35-45 API range, which includes most of the highest valued crudes such as Brent and WTI. Tim FitzgibbonMore API

API = (141.5/Specific Gravity) - 131.5
Barrels of Ekofisk crude oil per metric ton
In the oil industry, quantities of crude oil are often measured in metric tons. Ekofisk 7.51 bbl per MT.
Ekofisk Sulfur: 0.23%
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.

Ekofisk Specific gravity 0.837
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 Ekofisk
