Brazilian oil supermajor Petrobras announced that in 2022, it injected a record 10.6 million tons of CO2 underground.
The amount corresponded to roughly a quarter of the total amount of carbon emissions injected by the oil and gas sector worldwide throughout 2022.
The carbon dioxide injected by Petrobras was used for the process known as enhanced oil recovery or EOR and is said to reduce the overall greenhouse gas (GHG) emissions from oil production, while also increasing production efficiency.
Furthermore, in the experience of Petrobras, the use of CO2 capture technology in EOR also helps lower the cost of oil production and demonstrates that it is safe to use in the operations of the oil and gas sector.
The carbon capture, utilization and storage (CCUS) operations of Petrobras take place at all 21 of the company’s platforms in the Santos Basin.
