Crude oil assay

Okay, kiddo, let me explain to you what is crude oil assay in a very simple way.

Crude oil is a black, sticky liquid that comes from the ground. But not all crude oil is the same. It can be different depending on where it comes from and what it is made up of. So, to understand better what we can do with it, we need to do a test called a "crude oil assay".

An assay is like a way to check what is in something. Imagine a cookie, we can check how much sugar, flour, and eggs are in it to make sure it tastes good. It's kind of like that, but with crude oil.

So, scientists take a small sample of the crude oil and they put it in a special machine that can measure different things like how heavy or light the oil is, how much sulfur it has, and even what kinds of chemicals are in it. They do this because it's important to know these things to figure out what we can make from the oil.

For example, if the oil has a lot of sulfur, it may not make good gasoline for cars. But if it has less sulfur, it can be used to make jet fuel for airplanes. And if it has a lot of heavy chemicals, it may be better to use it to make asphalt for roads instead of gasoline or jet fuel.

So, in summary, crude oil assay is a test that helps us understand what's inside the oil so we can figure out ways to use it. It's like making a recipe for cooking with oil, but we need to know what's inside it first.
