Lack of climate policy and CO2 markets along with a global economic slowdown suggest that we need to rethink our approach to demonstrating CCS at a commercial scale. Austerity measures make it likely that public funding will be tight in coming years, and there is a striking need to ensure that limited funds are spent optimally. Quantitative tools exist for aiding decision making under uncertain...

Geological sequestration of CO2 through Enhanced Oil Recovery (EOR) presents an opportunity to achieve significant emissions reductions. However, there is considerable uncertainty over the amount of CO2 that can be stored over the economic life of an EOR project. This paper presents the development of a model that provides first-order cost estimates, sensitive to key site-specific or project-sp...

The potential of storing greenhouse gases in geological formations in the northeast portion of the Williston Basin is being investigated by researchers involved in the IEA Weyburn CO2 Monitoring and Storage Project. This project is linked to a CO2 miscible flood EOR program operated by EnCana Corporation in the Weyburn Midale Pool of southeastern Saskatchewan. A major component of the project i...

Lawrence Livermore National Laboratory (LLNL) is currently involved in a long term study using time-lapse multiple frequency electromagnetic (EM) characterization at a waterflood enhanced oil recovery (EOR) site in California operated by Chevron Heavy Oil Division in Lost Hills, California (Figure 1). The petroleum industry’s interest and the successful imaging results from this project suggest...

Residual oil zones (ROZs) could present a new, potentially large and commercially viable resource for Australia provide an avenue geological storage of carbon dioxide (CO2) through CO2 enhanced recovery (CO2-EOR). These reservoirs, which can contain moderate amount residual resemble water-flooded fields, be associated with conventional fields (brownfields) or occur no main pay zone (greenfields...

This paper is the first of a series that attempts to assess the possible health and safety risks associated with large scale CO2 sequestration in deep brine reservoirs. The approach is based on analysis of available data on the operational track record from CO2 transportation and injection associated with enhanced oil recovery (CO2-EOR) in the US. This paper is particularly concerned with ident...
