The sulfur content. The higher the amount of sulfur the harder it is to refine. And yes they used to taste and smell it to judge the sulfur content.

Correct. The well's we drill via Dpps in South Texas are Texas Light Sweet crude. It is easer to refine as well.
Brent is thicker and harder to refine.
Same with Shale....oil found in Shale.
Oil and Gas come together......as well.
Sometimes there is very little oil and it turns out to be a gas well, other times far more OIL, just flair off the gas...and sometimes you hit both. And many times you find nothing but water!
