Oil is classified as light, medium, heavy or extra heavy. Light and medium oil can flow naturally to the earth's surface and is generally extracted from the ground using vertical drilling and pumping – this includes Canada's offshore oil. Some light oil is trapped in "tight" (non-porous) rock formations, usually shale.

Iron is an essential element for all forms of life and is non-toxic. The average human contains about 4 grams of iron. A lot of this is in haemoglobin, in the blood. Haemoglobin carries oxygen from our lungs to the cells, where it is needed for tissue respiration. Humans need 10–18 milligrams of iron each day.
