  1. 1. Is There a “New Dawn” for CO 2 -EOR? Presented at WY EOR task force meeting July 25, 2006 Casper, WY Dag Nummedal Colorado Energy Research Institute Colorado School of Mines Golden, CO
  2. 2. View of the SPE Forum, Broomfield, June 30, 06 <ul><li>Consensus is yes! </li></ul><ul><ul><ul><li>Large amounts of CO2 will be generated in the future (GTL, coal gasification, coal to liquids, heavy oil SAGD, gas fields, oil shale); supply for EOR will increase </li></ul></ul></ul><ul><ul><ul><li>CO2 is valuable commodity for EOR purposes. Now scarce in the US </li></ul></ul></ul><ul><ul><ul><li>CO2 is waste for sequestration folks – resource to EOR ( different ‘drivers’ ) </li></ul></ul></ul><ul><ul><ul><li>Costs/Fiscal regimes will evolve to make CO2 EOR attractive; e.g. cap and trade </li></ul></ul></ul>
  3. 3. Present : use ‘ natural’ CO 2 for EOR Goal : use power plant CO 2 for EOR and sequestration CO2 for EOR in the Rocky Mountains

  7. 7. Questions?
  8. 8. Japan’s CO2 Storage Commitment <ul><li>CLIMATE: Japan to establish underground CO2 storage </li></ul><ul><li>Japan plans to set up facilities around the world to capture carbon dioxide from industrial operations and store it underground, the Japanese Ministry of Economy, Trade and Industry announced yesterday. </li></ul><ul><li>The ministry said it aims to use a CO2 capture and storage technology called CCS that reduces CO2 emissions into the atmosphere by 200 million tons per year, a sixth of current domestic CO2 emissions. Japan would store half of the CO2 in country and the other half abroad. </li></ul><ul><li>Not only does Japan hope to reduce its own emissions from CCS, it hopes to employ the same technology outside of Japan alongside natural gas production. The ministry said it hopes to start obtaining carbon credits from developing countries with CCS technology by 2010. </li></ul><ul><li>Pending international rules should establish how to count developed nations' CO2 reduction using CCS technology in developing countries along with developed nations' own reductions ( Japan Times , June 20). </li></ul>
  9. 9. Japan’s Major Storage Comitment - 2 <ul><li>Burying CO2 not 'silver bullet' to combating global warming, expert says </li></ul><ul><li>While energy firms around the world are heavily investing in projects to bury carbon dioxide, it is a costly venture that has the overall effect of a pinprick in the world's total emissions, an International Energy Agency expert said yesterday. </li></ul><ul><li>&quot;It's expensive ... this can be one solution among many to global warming [but] it's not going to be a silver bullet,&quot; Kelly Thambimuthu said during a carbon dioxide conference in Trondheim, Norway. </li></ul><ul><li>Projects in Norway, Australia, Scotland and the United States tout goals of burying as much as 15 million metric tons of CO2 per year, a fraction of the 25 billion metric tons of emissions globally every year. A 500-megawatt coal-fired power plant emits about 3 million metric tons per year. </li></ul><ul><li>Additionally, the high cost of storing CO2 underground, when compared with the cost of carbon credits, does not make storage cost-effective. Thambimuthu said that in Europe for storage to be economically viable the cost for a carbon credit would have to rise from its current $18.99 per metric ton of CO2 to at least $30 per metric ton or higher (Alister Doyle, Reuters/ New Zealand Herald , June 20). </li></ul>
