Report claims U.S. can curb carbon emissions while boosting domestic oil production

May 24, 2011

A report from the Massachusetts Institute of Technology (MIT) and The University of Texas at Austin urges the U.S. to accelerate efforts to pursue carbon capture and storage (CCS) in combination with enhanced oil recovery (EOR), a practice that could increase domestic oil production while significantly curbing emissions of carbon dioxide (CO2).

For decades the has used CO2 to extract oil from mature fields, often relying on purchased CO2 from natural sources. The idea of seeking CO2 from industrial sources, such as coal- and natural gas-fired electricity plants, has gained currency because of about .
 
Widespread adoption of combining with carbon capture and storage faces major hurdles, including development of infrastructure, regulation and economic incentives to manage supply and demand of CO2.
 
The report, "Role of Enhanced Oil Recovery in Accelerating the Deployment of Carbon Capture and Sequestration," the result of a symposium conducted by the MIT Energy Initiative and the Bureau of Economic Geology at The University of Texas at Austin, contends the U.S. can overcome these obstacles with sustained research and policy leadership.
 
According to the report, the potential for storage of carbon emissions through enhanced oil recovery is vast. Scientists believe the principal zones for combining EOR and CCS could accommodate 3,500 gigawatt-years-equivalent of CO2 from power plants. This represents about 15 years of current total output of CO2 from U.S. coal plants. Recent research suggests the potential for even greater capacity in the Permian Basin of West Texas.
 
As a tool for enhanced oil recovery, CO2 injected underground could boost domestic oil production by as much as three million barrels a day by 2030, according to one estimate, an increase of more than 50 percent over current levels. Such a boost to U.S. energy security would simultaneously help reduce the country's carbon footprint.
 
In a summary for policymakers, Ernest J. Moniz, director of the MIT Energy Initiative, and Scott W. Tinker, director of the Bureau of Economic Geology, make the case for an organized national CO2-EOR program using anthropogenic CO2 to "kick-start larger-scale carbon sequestration in the U.S. and meet sequestration needs for a significant period if CO2 emissions pricing is introduced."
 
Use of anthropogenic CO2 for EOR has the potential, write the co-authors, to contribute to domestic energy production while accommodating national sequestration needs "for at least a couple of decades, quite possibly more."
 
Given the rough equivalence between the amount of CO2 the energy industry needs for and the amount produced by coal-fired electricity plants, the authors advocate "a serious look at scaling up CO2-EOR with government support."
 
Government support will be critical in part because of the complex factors that have to come together to facilitate EOR, including regulatory changes and development of a new pipeline system to get CO2 from industrial sources to oil-field sinks. First-mover CCS projects also face high financial hurdles requiring some form of financial incentives.
 
The authors strongly urge the Department of Energy to implement a comprehensive research and development program that:

• Supports ongoing research on the science and systems of CO2 storage as it relates to EOR.

• Provides a framework for the value propositions that will make CO2-EOR feasible for power plant, pipeline, and EOR operators and for the government.

• Puts forward principles for resolving regulatory issues.

• Maps out a phased implementation for CO2-EOR.

Unfortunately, carbon capture does not make a lot of sense and the influence of CO2 on Earth's continuously changing climate has not been verified.

With kind regards,
