Colombia Castilla crude oil Assay

Castilla API gravity: 18.8

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 Castilla crude oil per metric ton

In the oil industry, quantities of crude oil are often measured in metric tons. Castilla 6.68 bbl per MT.

Castilla Sulfur: 1.97%

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.

Castilla Specific gravity 0.941

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.
