Water Injection - Offshore Oil & Gas - Episode 02
Ganesh Piping・2 minutes read
Enhanced oil recovery involves steam for tertiary recovery and water injection for secondary recovery, with CO2 and water creating a soda effect to extract hydrocarbons trapped in rock formations. The process uses a donkey pump to separate hydrocarbons from water and impurities for further processing.
Insights
- Water injection plays a vital role in both secondary and tertiary oil recovery stages by utilizing pressurized water to displace hydrocarbons from reservoirs, significantly increasing oil production efficiency.
- The use of a CO2 and water mixture in tertiary oil recovery generates a soda effect, facilitating the extraction of hydrocarbons trapped in rock formations, demonstrating an innovative approach to enhancing oil recovery methods beyond traditional techniques.

What is enhanced oil recovery?
Enhanced oil recovery involves using high-pressure steam and water injection techniques to extract hydrocarbons from reservoirs.
How does water injection aid in oil recovery?
Water injection is used in secondary oil recovery to pressurize and push hydrocarbons out of the reservoir.
What is the purpose of carbon dioxide injection in oil recovery?
Carbon dioxide injection, combined with water, creates a soda effect to release trapped hydrocarbons from rock formations.
What is the role of a donkey pump in oil recovery?
A donkey pump is used to collect hydrocarbons extracted during the tertiary oil recovery stage for further processing and separation.

Enhanced Oil Recovery Techniques Explained
- Enhanced oil recovery involves two stages: first, using high-pressure steam for tertiary oil recovery, and second, utilizing water injection techniques for enhanced oil recovery. Water injection is a crucial part of secondary oil recovery, where pressurized water is used to push hydrocarbons out of the reservoir.
- In the tertiary oil recovery stage, a combination of carbon dioxide (CO2) and water injection is employed to extract hydrocarbons. The CO2 and water mixture creates a soda effect, helping to release hydrocarbons trapped in rock formations, which are then collected using a donkey pump for further processing and separation from water and impurities.
