Can we use CO2 in a beneficial way?
EOR has the answer
With over 40 years of experience, Oxy is the largest injector of carbon dioxide for enhanced oil recovery (CO2 EOR) in the Permian Basin and among the largest globally.
What is Enhanced Oil Recovery (EOR)?
Enhanced Oil Recovery (EOR) is a process in which CO2 is injected into a producing oil field to help improve the reservoir’s operational, financial and environmental performance. Hydrocarbon-producing rock is porous. Injected CO2 displaces oil and gas trapped inside this porous rock—and then gets trapped itself to an extent.
This technique traps CO2 permanently in the reservoir while producing oil more efficiently. Studies show that this process gives the operation around 70 percent lower net emissions than traditionally produced oil and gas. For Oxy's highly efficient operations, that can lead to Net-Zero Oil.
Why is Oxy unique in EOR operations?
We've been doing this for decades. Consider that Oxy:
How does EOR make Oxy part of the climate solution?
Because we’ve had this EOR infrastructure in place for decades, we can now replace sourced CO2 with captured CO2. This vast storage potential means the world has a place to put all this human-made CO2 we don’t want in the atmosphere.
Pairing new carbon capture technologies and techniques with our vast legacy of EOR and CO2 investment could be a game-changer in the fight against climate change. And our ongoing effort is just the beginning. The United States alone has around 8,600 gigatonnes (Gt) of geologic CO2 storage capacity within underground reservoirs, according to U.S. Department of Energy's Carbon Atlas V publication.

Certified by the U.S. EPA
Oxy was the recipient of the nation’s first two United States Environmental Protection Agency certified Monitoring, Reporting and Verification (MRV) programs for CO2 injection. Awarded for our work in EOR operations within the Permian Basin, we now have three facilities with such stringently managed regulatory activity.
- 2015 Denver Unit
- 2017 Hobbs Unit
- 2021 West Seminole San Andres Unit
These MRV programs double-check that the CO2 injected into these oil and gas reservoirs is being stored safely and permanently. This third-party verification and reporting ensures total transparency and accountability today and as the use of permanent geologic CO2 storage scales in the future.
