Nigeria Erha crude oil Assay
Erha API gravity: 33.7
Anything below 15 API would be considered an extra-heavy crude. Tim FitzgibbonMore API

API = (141.5/Specific Gravity) - 131.5
Barrels of Erha crude oil per metric ton
In the oil industry, quantities of crude oil are often measured in metric tons. Erha 7.34 bbl per MT.
Erha Sulfur: 0.18%
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.

Erha Specific gravity 0.857
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 Erha
