The Role of CO2 Enhanced Oil Recovery In Ohio’s Economy and Energy Future

The original article does not contain bold or highlighted text, that has been added by this blogger.

Other entries on this blog refer to EOR as the easiest way to get CO2 into a community without their opposition so they can go ahead and build their CO2 storage areas. Please read past entries to find those entries. EOR is suspect.

Note the reference to CO2 used for EOR - "Storage" = Sequestration

From the above link (2008)

I. Purpose of the study

"The Pew Center on Global Climate Change seeks to explore the potential development and use of coal gasification and carbon capture and storage (CCS) technology in Ohio. Primary benefits of developing and deploying CCS in Ohio include power generated using readily available coal while achieving substantial reductions in greenhouse gas emissions from this generation. Additional benefits include many chemical by-products, especially captured CO2 which can be used commercially for Enhanced Oil Recovery (EOR). Prior research completed by Kleinhenz & Associates for the Pew Center analyzed the economic activity factors related to coal gasification and how the location of a number of key support industries in Ohio could provide the state with a competitive advantage in this area.i This prior research did not address injection of CO2 into deep saline formations (sequestration), or storage of CO2 in association with EOR. The study also did not offer an estimate of the required pipeline network or the industries and employment affiliated with development of an Ohio CO2 market. Ohio firms have been major suppliers of the heavy equipment utilized in the oil and gas industry throughout North America. A CO2 EOR and sequestration industry would utilize similar types of heavy equipment in large volumes.

Further development of coal-gasification plants in Ohio depends upon a full understanding of the development of a CO2 market. The CO2 byproduct can be captured during the gasification process and transported via pipeline and injected in an oil or gas well to enhance recovery. With minor modifications to the process, volumes of CO2 stored through EOR can be documented. Carbon dioxide might also be sequestered (long-term) in a suitable underground reservoir containing no hydrocarbons (deep saline formation). Texas serves as a good example of a state in which the commercialization of CO2 for enhanced oil recovery as well as state regulations are well defined, while the CO2 industry in Ohio is neither defined nor commercialized. However, the Ohio House and Senate recently adopted an energy bill that would establish a regulatory framework for CO2,ii and provide credits to utilities that installed equipment for capturing carbon dioxide."

Again note - "Potential CO2 sinks" -- Sinks = CO2 Sequestration (Storage)

"Estimating the potential impact on Ohio-based industries requires a framework that includes the creation of a conceptual Ohio CO2 pipeline network. This network links proposed major sources of CO2 – such as coal gasification plants and biofuel plants – to some potential CO2 sinks with strong potential as EOR sites."
