Carbon Dioxide Enhanced Oil Recovery and Associated Retention

The USGS has developed a new methodology for the national assessment of technically recoverable oil resources that may be produced by using current CO2-EOR technologies.

The objective of this research task is to conduct a national assessment of recoverable oil related to COinjection. The amount of CO2 stored (utilized) during the hydrocarbon recovery process will also be evaluated.

Utilization of CO2 for enhanced oil recovery (EOR) in existing or depleted hydrocarbon reservoirs can increase the U.S. hydrocarbon recoverable resource volume and prevent wasteful CO2 release to the atmosphere.

The Energy Independence and Security Act (EISA, Public Law 110-140) of 2007 authorized the USGS to conduct a national assessment of geologic storage resources and to evaluate the national technically recoverable hydrocarbon resources resulting from CO2 injection and related storage (CO2-EOR).

The USGS recently completed the national CO2 storage assessment (see U.S. Geological Survey Geologic Carbon Dioxide Storage Resources Assessment Team, 2013); however, an evaluation of recoverable hydrocarbons (oil) related to CO2 injection was delayed to allow the USGS time to build a comprehensive CO2-EOR database and to develop an assessment methodology to evaluate the recovery potential for oil related to CO2 injection.

The USGS CO2-EOR assessment will build upon previous technical/economic evaluations conducted by industry, government, and academic organizations; however, the USGS assessment will be of the total technically recoverable oil resources, and will not include a minimum economic cutoff.

Previous assessments of CO2-EOR recoverable resources have included economic constraints and vary widely with some estimates of over 100 billion barrels of technically recoverable oil. The national resource of technically recoverable oil resulting from CO2 injection on a non-economic basis is unknown.
