  1. Pilot Production Performance Update And Utilization Factor Determination

  2. Outline • Battery production update as of October 17, 2002 • Comparison production Performances between Interior wells and ET O’Daniel A-1 • Utilization factor determination • Development of database using OFM

  3. Battery Production Update As Of October 17, 2002

  4. Comparison production Performances between Interior wells and ET O’Daniel A-1

  5. Effect of gas rate on oil production at O’Daniel A-1

  6. - Epics

  8. Utilization Factor

  9. Utilization Factor Based on our gas compositional analysis we found that production rate from interior wells, ET O’Daniel A-1 and Brunson F-1 affected by by CO2 flooding. Then, the net and gross utilization factors calculations are taken on those wells following the equation below: Gross Utilization: Total CO2 Injected / Total oil produced Net Utilization: (Total CO2 Injected – Total CO2 produced)/Total oil produced

  10. Utilization Factor (Cont’d) • Total CO2 injected : 122, 687 MSCF • Total CO2 produced at interior wells, ET O’Daniel A-1 and Brunson F-1 : ~63014 MSCF • Total oil produced at ET O’Daniel and Brunson F-1 (see decline analysis) : ~6744 STB Gross Utilization: 18.2 MSCF/STB Net Utilization: 8.8 MSCF/STB

  11. Gross Utilization Calculation in other CO2 Pilots (Assuming Bo=1.3 and Sw=0.65)

  12. Is O’Brien B-1 production affected by CO2 flooding?

  13. Database in OFM

  14. Example of Historical Oil Production

  15. Example of Tracer data
