Malaysia Tapis crude oil Assay
Tapis API gravity: 46
Crudes lighter than 45 are typically considered extra-light crude or condensates and are valued lower than light crude because they contain a lot of light ends such as propane and butane. Tim FitzgibbonMore API

API = (141.5/Specific Gravity) - 131.5
Barrels of Tapis crude oil per metric ton
In the oil industry, quantities of crude oil are often measured in metric tons. Tapis 7.89 bbl per MT.
Tapis Sulfur: 0.02%
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.

Tapis Specific gravity 0.797
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 Tapis
