Excerpt from OilGas 24 Scandinavian Oil and Gas Magazine Statoil, Shell assemble carbon frontrunners courtesy Statoil A mobile carbon-scrubbing construction will be tested in May at the Shell-Statoil carbon-dioxide project at Risavika, just outside Stavanger, it was learned Tuesday. Canadian supplier Cansolv is one of three suppliers to the full-scale Halten CO2 project at Tjeldbergodden central Norway. Mitsubishi Heavy Industries and Fluor are the other carbon sequestration companies employed in the tests. The companies are vying for a contract to stop 2.5 million tonnes a year from flowing into the atmosphere at a future 850 Megawatt gas-plant on the Tjeldbergodden site…. … Cansolv is dwarfed by the two industrial giants, but “sits on solid knowledge on the separating of carbon from natural gas”, although the plan is to separate 85 percent of the C02 from the power plant’s exhaust passages. • http://www.oilgas24.com/bm/Gas/statoil-shell-assemble-carbon-frontrunners.shtml

The Power Industry is the World’s Greatest Producer of CO2 • Greatest potential for CO2 Capture is from power plants • Current EOR CO2 injected is 50 MMtpy • Required CO2 capture by 2030 is 7,000 MMtpy
Geological Storage Reservoirs Have the Greatest Capacity for Captured CO2 For Example: • In North America, the top 500 sources emit 3.3 Gt/yr • 3.1 Gt CO2/yr can be stored in formations within 150 km of each source Total storage capacity Is much greater Source; IEAGreenhouse
History of PCOR* in the US IllustratesHow a CCS Program can be Executed The United States DOE established the National Energy Technology Laboratory (NETL) to manage seven partnerships • Phase 1 studies identified sources and sinks 2003 - 2005 • Phase 2 studies executed research programs to • study key sequestration strategies - 2005 to present *Plains CO2 Reduction Partnership
PCOR Partnership - Sources of CO2 • PCOR’s data base maps 1,360 sources by industry type and volume of CO2 emitted annually Source www.undeerc.org/pcor
PCOR Partnership - Sinks for CO2 • Area reservoir structures, and oil reserves are carefully evaluated Source www.undeerc.org/pcor
Testing Phase Projects • Weyburn injection project • Pinnacle reef injection project • Wetland carbon sequestration study • Deepwell injection project • Unminable coal reserve sequestration Reservoir evaluation Can take 2+ years.
