More oil, less CO2

Weyburn Unit Stats - Cenovus

Field Size:
70 square miles
Projected CO2 incremental oil recovery:
155 million barrels
   
Oil Type:
Medium sour crude
Projected CO2 stored:
30+ million tonnes* (gross)
26+ million tonnes (net)
   
Original oil in place:
1.4 billion barrels
 
   
Oil recovery (prior to using CO2 for enhanced oil recovery):
370 million barrels

*equivalent to removing
over 6 million cars
off the road for a year

Production Graph

As this historical oil production graph illustrates, production at the Weyburn field has increased by approximately 13,000 barrels per day as a direct result of CO2 injection. Update: At the end of 2005, incremental oil production due to CO2 injection was higher than initially projected (see yellow star).

Midale Unit Stats - Apache

Field Size:
40 square miles
Projected CO2 incremental oil recovery:
67 million barrels
   
Oil Type:
Medium sour crude
Projected CO2 stored:
10+ million tonnes* (gross)
8.5+ million tonnes (net)
   
Original oil in place:
515 million barrels
 
   
Oil recovery (prior to using CO2 for enhanced oil recovery):
154 million barrels

*equivalent to removing
over 2 million cars
off the road for a year

Production History

This production history and forecast for the Midale field looks nearly identical to the Weyburn field graph, further illustrating the positive impact CO2 injection has on oil recovery.
