Bitumen is also frequently called tar or pitchâthough, properly speaking, tar is a byproduct of the carbonization of coal and pitch is actually obtained from the distillation of coal tar. Bitumen is defined by the U.S. Geological Survey as an extra-heavy oil with an API gravity less than 10Â° and a viscosity greater than 10,000 centipoise.

Oil sands are a mixture of sand, water, clay and bitumen. Bitumen is oil that is too heavy or thick to flow or be pumped without being diluted or heated. At 10Â° C/50Â° F, bitumen is hard as a hockey puck. Some bitumen is found within 70 metres (200 feet) of the surface, but the majority is deeper underground.
