1. Chapter
How do we get oil
out of the ground?
4
…Very Carefully.

2. When we have a 3 Dimensional
Picture…
2Of an Oil and Gas Reservoir…

3. 3
Like the
HIBERNIA
Field…

4. 4
We know
to drill
the first
wells.
thebest places…

5. Some OILFIELDS…

6. Have a ‘GAS ‘CAP’…

7. An ‘OIL ‘LEG’…

8. And a WATER ‘LEG’…

9. Gas
Oil
Water

10. Wells are frequently
drilled in ‘pairs’…

11. One is drilled into the
‘Oil Leg’…

12. Another is drilled into
the Water Leg’…

13. PRODUCER-INJECTOR PAIR
This is referred to as a…

14. Wells will be drilled into that too…
If there is GAS CAP…

15. The wells will be ‘LOGGED’…
To ‘confirm’ the 3D Model

16. “CASING” will be ‘run in’…
It is the ‘plumbing’ of the OILFIELD…

17. It needs to be PERFORATED…
Put holes in the steel pipe…To allow the FLUIDS to FLOW…

18. Perforating ‘guns’ are lowered
into the wellbore…

19. Perforating ‘guns’ are ‘fired’…

20. A perforating gun detonated at the surface.
Mannequin on the left for scale.
This is a simulation of what
would happen if the Perforating
‘guns’ are ‘fired’… at surface.

21. The explosion blows holes through the steel
CASING, and out into the RESERVOIR ROCK…

23. Water is INJECTED into the RESERVOIROil is PRODUCED out of the RESERVOIRGas is INJECTED into the RESERVOIR

The HIBERNIA
Field Has > 70
wells…
Has ~ 40
OIL wells…
Has ~ 25 WATER
Injectors…
Has ~ 7
GAS Injectors…

27. 27
The HIBERNIA
Field
Has produced
~900 MILLION Barrels of
OIL
As of end of March 2014…

Terra Nova and White Rose oil production is from large specialized ‘ships’
called FPSO’s (Floating, Production, Storage and Offloading).
