  1. Review of field projects under the GCCC umbrella

  2. Critical role of field projects for GCCC • “Obtain additional funding for field demonstrations at an appropriate scale to demonstrate competence in measurement, monitoring, and verification (MMV) and project economic viability” • From original proposals for BEG/BP. Kinder Morgan “ Carbon Management Center” December 2002

  3. Field projects integrated with paper studies • Field tests validate theoretical and model predictions and advance understanding rapidly. Four GCCC goals have field components • Goal 2.0: To Develop Selection Criteria for Commercial CO2 Sequestration • Goal 3: To Define an Adequate and Reliable Monitoring and Verification Strategy Applicable to Long Term Storage • Goal 4: Evaluation of Sources Risk and Liability Potentially Associated with CO2 Sequestration • Goal 5: Evaluation of Economic Potential of CO2 to Enhance Oil and Gas Recovery in the Gulf Coast • Field tests provide access for decision makers to see how the process works

  4. GCCC Field Tests for Monitoring and Verification Technologies SECARB Phase II&II Cranfield Frio Test Site SACROC

  5. Status and details of field tests

  6. Frio I and II Key results • First US brine sequestration test • Successful tool deployment – CO2 movement quantified • Good match to numerical models -GEM TOUGH2, geochemical models • New tool development – U-tube and Continuous Active Source Seismic Monitoring (CASSM) • Precedent for other tests and EPA regulations

  7. Observation well Injection well

  8. SECARB Phase II (Cranfield Oil ring) Overarching Research Focuses (1) Sweep efficiency – how effectively are pore volumes contacted by CO2? • Important in recovery efficiency in EOR • For storage – what is capacity of subsurface? Prediction of plume size (2) Injection volume is sum of fluid displacement, dilatancy, dissolution, and rock+fluid compression • Tilt to start to understand magnitude of dilatancy • Bottom hole pressure mapping to estimate fluid displacement (3) Effectiveness of Mississippi well completions regs in retaining CO2 in GHG context • Above zone monitoring

  9. PHASE II OBSERVATION WELL LOCATION Monitor Sand Marine Shale Seal 375’ Injection Sand 3 MMCFD Injection rates Phase II : ½ Million Tons/yr Phase III : 1-1.5 Mt/yr

  10. Phase III Research Focuses • Large volume - Multiple wells • Brine downdip from production • Follow-on from Phase II issues • Tilt, pressure, plume interaction • Follow-on from Frio test results • Direct measurement of plume evolution with CASSM – a “trip wire technology” • Dissolution of CO2 into oil and brine

  11. Integration of Research: Theoretical Approaches Through Commercialization Commercial Deployment by Southern Co. Contingency plan Parsimonious public assurance monitoring CO2 saturation and extent size correctly predicted by model Toward commercia-lization CO2 retained in-zone- document no leakage to air-no damage to water Pressure (flow plus deformation) correctly predicted by model CO2 saturation correctly predicted by flow modeling Hypothesis tested CO2 saturation measured through time – acoustic impedance + conductivity Tomography and change through time Surface monitoring: instrument verification Groundwater program CO2 variation over time Tilt, microcosmic, pressure mapping Acoustic response to pressure change over time Field experiments Above-zone acoustic monitoring (CASSM) & pressure monitoring 3- D time lapse surface seismic Dissolution and saturation measured via tracer breakthrough and chromatography Sensitivity of tools; saturated-vadose modeling of flux and tracers Lab-based core response to EM and acoustic under various saturations, tracer behavior Advanced simulation of reservoir pressure field Theory and lab

  12. SACROC goals • Documented any measurable impact to water after 35 years of injection • Conformance of CO2 • Check this with Becky
