  1. SECARB Phase II Field Tests in Coal of the Black Warrior Basin Jack C. Pashin Director, Energy Investigations Program Presented by Nick Tew State Geologist Geological Survey of Alabama http://www.secarbon.org http://portal.gsa.state.al.us/CO2/CO2.htm http://www.netl.doe.gov/

  2. DOE SEQUESTRATION PROGRAM

  3. GEOLOGIC CARBON SINKS Saline aquifers Oil and gas reservoirs Coal GOALS AND BENEFITS Reduce greenhouse gas emissions Develop market-based solutions Enhance oil and gas recovery Enhance coalbed methane recovery Create and preserve jobs

  4. REGIONAL PARTNERSHIPS Hyman (2005)

  5. PRINCIPAL SPONSOR U.S. Department of Energy - NETL PROGRAM TEAM SSEB, Virginia Tech - Contractual Geological Survey of AL - Tech Lead,Geology University of Alabama - Engineering Southern Company/EPRI - MMV Mississippi State University/ICET - MMV Univ. British Columbia - Analytical Oak Ridge National Laboratory - Analytical ARI - Reservoir Simulation CCP2 - Reservoir Modeling Denbury Resources - CO2

  6. WHY COAL? CO2 capacity of 90 Gt (45 yrs) in US. CO2-ECBM potential of about 4.3 Tcm (150 Tcf) provides economic incentive. Shallow reservoir (150-1500 m) with low P&T can reduce compression cost Coal is abundant near major CO2 emission sources, such as power plants.

  7. SECARB II OBJECTIVES Assess capacity/potential of geologic sinks (saline aquifers, O&G reservoirs, coal). Conduct field tests to validate sequestration and CO2-enhanced recovery technology. Conduct MMV programs to ensure safety, environmental protection. Conduct outreach/tech transfer to facilitate commercialization/public acceptance

  8. POTTSVILLE ISOTHERMS, ALABAMA

  9. Area of Interest Power plant

  10. Blue Creek Field

  11. CBM WELL DEEP MINE

  12. CO2-ECBM TECHNICAL FEASIBILITY ALABAMA Area of Interest Sequestration > 6 Tcf ECBM = 0.6-1.2 Tcf

  13. POTTSVILLE FORMATION Cassidy 30-2-119 Blue Creek Field Tuscaloosa Co., AL

  14. PERMEABILITY-DEPTH RELATIONSHIP POTTSVILLE FM. McKee et al. (1988)

  15. RESERVOIRS AND HYDROFRACS

  16. BLACK WARRIOR PILOT SITE PLAN

  17. LI-COR SURFACE MONITORING Southern Company

  18. CAVITY RINGDOWN SPECTROMETER Surface monitoring - Isotopic analysis of 12/13C Institute for Clean Energy Technology, Mississippi State University

  19. CO2 and Alabama Coal High CO2 capacity. CO2-Enhanced Coalbed Methane Potential. Shallow reservoirs (150-1500 m) with low temperature and pressure . Coal in proximity to CO2 emission sources, i.e., power plants.
