Canada WCS crude oil Assay

WCS API gravity: 20.1

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 Fitzgibbon

API = (141.5/Specific Gravity) - 131.5

Barrels of WCS crude oil per metric ton

In the oil industry, quantities of crude oil are often measured in metric tons. WCS 6.74 bbl per MT.

WCS Sulfur: 3.64%

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.

WCS Specific gravity 0.933

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.
