Topic

Oil sands are a combination of clay, sand, water, and bitumen, a heavy black viscous oil. Oil sands can be mined and processed to extract the oil-rich bitumen, which is then refined into oil. The bitumen in oil sands cannot be pumped from the ground in its natural state; instead oil sand deposits are mined, usually using strip mining or open pit techniques, or the oil is extracted by underground heating with additional upgrading.
