Â­ Crude oil is the term for unprocessed oil, the stuff that comes out of the ground. It is also known as petroleum. Crude oil is a fossil fuel, meaning that it was made naturalÂ­ly from decaying plants and animals living in ancient seas millions of years ago -- most places you can find crude oil were once sea beds. Crude oils vary in color, from clear to tar-black, and in viscosity, from water to almost solid.
Where is Petroleum Found? Oil and natural gas reserves are found in many parts of the world. In the past, demand was low and reserves were easy to find. In fact, the first users of oil depended on surface seepage for their supplies. However, as demand has increased, all the easy-to-find oil has been used. Today, oil exploration takes place in some of the most challenging places on earth.
