Not all crude oil is the same...it can be sweet or sour and light, medium, or heavy. This video talks about processes that generate the sour, extra heavy crude oil in Venezuela's Orinoco extra-heavy oil belt. This oil actually has travelled a huge distance to end up where it is now, but the "sour" part of its composition goes back to its roots. MS Paint diagrams tell the story and give a general idea of how this specific type of crude oil occurrence develops.
