15. Oil-Sands
Bitumen:
A heavy viscous crude oil form
Similar to coal

16. Oil-Sands
Why oil sands are important

17. Oil-Sands
Canada:
Almost 3rd largest world oil reserves there.

18. Oil-Sands
Canada:
97% of oil reserves are tapped with sands.

19. Oil-Sands
Canada:

20. Oil-Sands
20% of oil sands are close to Earth surface.

21. Oil-Sands
Canada Oil Sands
Have drawn attention
For 200+ years

22. 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”

23. Oil-Sands
In 20th Century:
Efforts to exploit these oil sands began

24. Oil-Sands
Oil Sands Recovery
•Open Pit Mining
•In-Situ Methods

25. Oil-Sands
Oil Sands Recovery
Open 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

26. Oil-Sands

28. Oil-Sands
Oil Sands Recovery
In-Situ Methods
Usually for reserves below 200ft

29. Oil-Sands
Oil Sands Recovery
In-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
