Geology

The first necessity in the heavy oil industry is FINDING heavy oil.  We need the skills of the geologist and many other scientists and technicians to understand the structure of the Earth and the nature of oil deposits and then use this understanding to predict where heavy oil is located

Crudey does GeologyCrudey, the Heavy Oil drop says, Welcome! Did you know that you and I are related? Yes, we’re both based on carbon. I’m a hydrocarbon and you’re a carbon based life form. That’s what gave scientists the clue that petroleum actually derives from living plants and animals.

Way back in the Lower Cretaceous Period, like 100 million years ago, there were lush jungles and the seas teemed with plant and animal life. When some of these plants and animals got covered with sand or mud, the process of becoming petroleum had begun. Sometimes this was due to mud slides, or shifting sand dunes, or even volcano blasts or meteors colliding with Earth and throwing up big clouds of dust. The deposits built up, layer upon layer, preventing further decay, and as layers were added on top, the pressure exerted by this overburden increased.   ... more from Crudey
