Oil sands | Suncor

Oil sands process and production. Oil sand is a mixture of bitumen, sand, clay and water. Because it does not flow like conventional crude oil which is a liquid, it must be mined or heated underground before it can be processed. Once the bitumen has been extracted, we upgrade it into higher-value synthetic crude oil, diesel fuel and other products.
