Oil-Sands
A mixture of
Sand + Clay + Minerals+
Bitumen+
others
Oil-Sands
Bitumen:
A heavy viscous crude oil formSimilar to coal

Why oil sands are important
Oil-Sands
Canada:
Almost 3rd largest world oil reserves there.
Oil-Sands
Canada:
97% of oil reserves are tapped with sands.
Oil-Sands
Canada:
Total Canada Reserves: 173 billion barrelsReserves In Oil Sands: 167 billion barrels
Oil-Sands
20% of oil sands are close to Earth surface.
Oil-Sands
Canada Oil Sands
Have drawn attentionFor 200+ years
Oil-Sands
Canada Oil Sands
Historical Background:In 1715
It was written in a journal that
“gums or pitch that flows out
of the banks of a river”
Oil-Sands
In 20th Century:
Efforts to exploit these oil sands began
Oil-Sands
Oil Sands Recovery
•Open Pit Mining• In-Situ Methods
Oil-Sands
Oil Sands RecoveryOpen Pit Mining
•Large shovels scoop oil sands into trucks•Trucks transfer it to crusher•Large clay pieces are broken•Oil sand is mixed with water•Then sent to separator

Oil Sands RecoveryIn-Situ Methods
•Some heat source is injected by directional drilling•Bitumen warms up and melts(may or may not)•Bitumen pumps out by horizontal well
