  1. Energy and the Environment:Tapping the Potential for Large Volume Storage of Carbon in the Gulf Coast Susan Hovorka Bureau of Economic Geology Jackson School of Geosciences The University of Texas at Austin

  2. Waste CO2 from combustion of fossil fuel is now released to the atmosphere Rather than releasing the CO2, it can be injected underground below and separated from potable water and isolated or sequestered from the atmosphere for thousands of years What is Geologic Sequestration?

  3. Power generation (IEA) Early sources (IEA data) Oil and Gas (USGS) Coal (USGS) Brine Aquifers >1000m U.S. Geologic Storage Potential

  4. Ozone non attainment Selected oil field that could benefit from EOR Existing CO2 pipeline Sources (dot size =release) Refineries and chemical plants Electric power plants Future CO2 pipeline Saline Formations Vision for the Future in Texas

  5. Field Pilot Project in the Houston Area • Inject and closely monitor CO2 injection and sequestration under ideal conditions • $3 million federal funding DOE • Test date: fall 2003 • 3,000 metric tons CO2 from BP’s Texas City refinery • Injected in a non-productive sandstone of the Frio Formation, • Research team: BEG, Texas American Resources, Sandia Technologies, Transpetco, Schlumberger, Geo-Seq (3 national labs), NETL

  6. An new well will be drilled near an existing well 3000 tons of food-grade carbon dioxide (CO2) will be trucked from the BP Texas City refinery and be injected 5000 feet deep into the Frio formation over period of a few weeks Closely monitor the movement of the carbon dioxide underground and at the surface to see how well the actual movement matches the computer model

  7. Downgoing Top Frio B Sand C Sand 100% CO2 0% CO2 Crosswell Seismic and VSP Will Image Interwell Region From. L. Myer, Lawrence Berkeley National Lab
