a deposit of sand saturated with bitumen.

Also called oil sands or bituminous sands. It is a combination of clay, sand, water, and bitumen (hydrocarbons), which is then refined into oil. Tar sand deposits are mined using strip-mining techniques.

Sand deposits containing petroleum or tar.

Mixture of sand, water, and heavy hydrocarbons.

Sedimentary rocks containing heavy oil that cannot be extracted by conventional petroleum recovery methods.

a combustible mixture of crude oil, sand and water. This mixture is considered a form of petroleum (fossil fuel) and will flow only when heated.

Hydrocarbon bearing deposits distinguished from more conventional oil and gas reservoirs by the high viscosity of the hydrocarbon which is not recoverable in its natural state through a well by ordinary oil production methods.

Tar sands, also referred to as oil sands or bituminous sands, are a combination of clay, sand, water, and bitumen. On average bitumen contains 83.2% carbon, 10.4% hydrogen, 4.8% sulphur, 0.94% oxygen, and 0.36% nitrogen.
