KSG007 gamma log_diff

  1. 1. ISSUES: Integrity of Gamma log <ul><li>ONWater’s Jens H.P. Norgaard has doubt on the gamma log collected @KSG007 </li></ul><ul><li>The doubtful depth is between 20 to 30m where there’s low reading and a high kick </li></ul><ul><li>A rerun has been requested by ONWater without clear justification </li></ul><ul><li>This PPT is a mean of discussion on the above issue </li></ul>
  2. 2. Gamma Log from TCGS & ELOG sonde collected@KSG007 and KSG008
  3. 3. TCGS SONDE LAYOUT
  4. 4. ELOG SONDE LAYOUT
  5. 5. 1. Depth: 20 -30m (see the right-most column only) Slide 6:Gamma log from TCGS sonde Slide 7: Gamma log from ELOG sonde
  6. 8. Gamma log data from KSG008 which is approx. 1.9km north of KSG007 is being compared to show a possible geology similarity between them.
  7. 10. Data from KSG008 2. Depth: 13 -23m (see the right-most column only) Slide 11:Gamma log from TCGS sonde Slide 12: Gamma log from ELOG sonde
  8. 13. <ul><li>Conclusion: Both tools basically provide a reliable gamma log data. The anomaly observed is possibly that of the subsurface and not of that of the tool and operators. A rerun wouldn’t be necessary here. </li></ul>
