ADNOC to expand CCUS technology to reduce environmental footprint and enhance oil recovery
Large increase in subsurface injection of CO2 will see about 5 million metric tonnes of the greenhouse gas collected every year and locked away safely underground.
The Abu Dhabi National Oil Company (ADNOC) is planning to significantly expand its use of Carbon Capture, Use and Storage (CCUS) technology to meet a six-fold increase in the utilisation of CO2, for Enhanced Oil Recovery (EOR), over the next 10 years. The volume of the greenhouse gas locked away underground will be equivalent to the CO2 emitted by more than one million motor vehicles each day.
To meet the increased demand for CO2, which will be injected into Abu Dhabi’s maturing oil reservoirs, ADNOC has drawn up plans to capture the greenhouse gas from its own operations. ADNOC aims to achieve up to 70 per cent ultimate oil recovery rate from its reservoirs, twice the global average, applying conventional recovery methods.
To date, ADNOC has stored approximately 240,000 metric tons of CO2, collected from Emirates Steel Industries, by injecting it into its reservoirs at Rumaitha and Bab oilfields to bolster oil recovery.
Starting in 2021, ADNOC will gradually increase the utilisation of CO2, expecting to reach 250 million standard cubic feet per day by 2027, by capturing additional CO2 from its gas processing plants and injecting it into different onshore oil fields.
Abdulmunim Saif Al Kindy, Director of ADNOC’s Upstream Directorate and Chairman of Al Reyadah said: “As we push forward plans to create value by maximizing oil recovery over the life time of our fields, we will increasingly utilise a range of Enhanced Oil Recovery technologies, of which carbon capture, use and storage is not only good for the environment but also makes sound business sense.
“Replacing rich gas with CO2 injection into ADNOC’s maturing fields will allow the more productive use of valuable clean-burning natural gas, whether for power generation, desalination or as petrochemicals’ feedstock. This is a prime example of how clean technology can be integrated with traditional energy to optimise resources and reduce the environmental footprint.”
