What are oil sands?

Oil Sands

Oil sands, tar sands or, more technically, bituminous sands, are a type of unconventional petroleum deposit. The oil sands are loose sand or partially consolidated sandstone containing naturally occurring mixtures of sand, clay, and water, saturated with a dense and extremely viscous form of petroleum technically referred to as bitumen (or colloquially tar due to its similar appearance, odour and colour). Natural bitumen deposits are reported in many countries, but in particular are found in extremely large quantities in Canada. Other large reserves are located in Kazakhstan and Russia. Total natural bitumen reserves are estimated at 249.67 billion barrels (39.694×10^9 m3) globally, of which 176.8 billion barrels (28.11×10^9 m3), or 70.8%, are in Canada.

Famous quotes containing the words sands and/or oil:

    Perchance the time will come when we shall not be content to go back and forth upon a raft to some huge Homeric or Shakespearean Indiaman that lies upon the reef, but build a bark out of that wreck and others that are buried in the sands of this desolate island, and such new timber as may be required, in which to sail away to whole new worlds of light and life, where our friends are.
    Henry David Thoreau (1817–1862)

    No skilled hands
    caress a stranger’s flesh with lucid oil before
    a word is spoken
    no feasting
    before a tale is told, before
    the stranger tells his name.
    Denise Levertov (b. 1923)
