Crude oil is typically found deep in the ground in most often limestone formations. It does not accumulate in lakes underground but is in the porous formations. There are different crude oils depending on their locations. The main differences between them is the API (specific gravity) and also their sulphur content.Crude which has very little sulphur is referred to as "sweet crude" and with hight sulphur content "sour crude". The gravity of course is most important as when it has a high gravity it is easier to refine and has a much higher gasoline content. The lower gravity crude demands more energy to refine and you don't get as much light product from it. The heavy crude will tend to give more distillate (diesel and Jet fuel ) along with bunker (black oil) and you can produce asphalt from this oil.Typically you can produce ethane methane propane butane light stream gasoline, jet fuel, diesel oil and fuel oil from crude oil. These products can also be taken to further steps of refining in order to produce more gasoline or improved qualities in the gasoline like octane improvement( called cat cracking process, or reforming) . Crude oil can also be found in sand formations even at the surface of the ground where it is called "Tar Sands". The largest tar sands deposits are found in Northern Alberta, Canada. The process to recover the oil from the sand is costly but worthwhile when the price of crude is high like today. It requires a lot of heat energy to separate the oil from the sand. Hopefully this is a help to you, I worked with crude oil for 45 years.

Crude oil is any oil pumped directly from its naturally occurring formation underground. It can be clear and thinner than water, or extremely dark black and thick as tar. Without getting extremely scientific on you, crude oil is "in" so many products it's impossible to name them. But not as "crude" oil. It has been refined to make gasoline, diesel, plastics, synthetic fabics, etc.

What's it u wanna kno?
CrudeOil- Extracted from underground reserves_ formed by decomposed organic material_animal and plant remains, etal.
Formed under bacterial, chemical, geological actions over millions of years.
Contains some minerals, sulphur... etc and several hundred types of hydrocarbons.
Crude from different sources may have different compositions owing to age, origin, reactions, nature of porous rocks thru which it has trickled, mineral matter in surroundings, etc
Usually a thick, viscous, smelly liquid, it is pumped out or gushes out of the 'wells'. Trade unit is 'Barrel'. It is then transported to the 'Refineries' where it is subjected to Cracking, fractional distillation etc to separate the various hydrocarbons eg gasoline, diesel, heating oil, furnace oil, tar, bitumen, petroleum coke, naptha, various plastics, etal.
Synthetic fibre, medicines, alcohols, lube oils, camphor, wax, most chemicals, etc have their origins in crude oil.
Its a huge thing.
Suggest refer wikipedia.com for details

it is observed as crude oil especially because of the fact a million) It has no longer been sophisticated into stable, usable oil (for autos and such) 2) The density of the crude oil is often distinctive. there is not any regularly happening for something to be observed as crude oil.

It has no manners and smells like sulfur.
