What Types of Crude Oil Lab Tests & Why?
When crude oil is extracted from earth crust, it needs to be tested for quality. It is also known as a crude oil assay which is the chemical evaluation of crude oil feedstock. No two crude oil types are identical, They have unique chemical and molecular characteristics. By collecting assay data, it helps to determine whether a crude oil feedstock is compatible with a particular petroleum refinery. It is a comprehensive assay. Types of Tests & Why API Gravity The American Petroleum Institute gravity stands for API which is a measurement of how light or heavy a petroleum liquid compared to water. If the measurement result comes more than 10, the oil is lighter than water, so it floats. If the measurement is less than 10, the oil is heavier than water, so it sinks. It is associated with the density of crude oil, Asphaltene The molecular substance found in crude oil, diesel fuel, lubricating oil, bitumen and gas oil. The molecule has the highest molecular mass and carb
