The oil life of a reservoir is significantly extended by using CO2 injection. CO2 injection used as artificial lift. Carbon dioxide in oppose to the vapors from coal.
Other forms of artificial lift can be to drill a horizontal well; initiate water injection; thermal recovery and gas injection to extend the life of the industry.
1. CO2 mixes with water to form carbonic acid (+)
2. Creates carbonic acid (+)
3. Attacks iron in carbon steel (-)
4. Fluid speed and compromising the integrity of components (+)
5. CO2 strips resins from asphaltene (+)
6. Releases asphaltenes that have a negative charge (+)
7. Asphaltenes attach to iron (positive charge) present in carbon steel (-)
8. Pump and tubing gets choked with asphaltene buildup (-)
9. Aromatics (+)
