Table T11. Logging operations summary, Hole U1383C.
| Date (2011) |
Time (h) |
Activity |
|---|---|---|
| 3 Nov | 0025 | Downhole logging operations start |
| 3 Nov | 0120 | On power up the tools string encountered a communications issue. The problem was located around the resistivity sonde (HRLA). Following some trouble-shooting, the HRLA sonde was removed from the tool string. |
| 3 Nov | 0255 | AMC II tool string run into hole and a downlog was started from surface to monitor the DEBI-t |
| 3 Nov | 0504 | Begin “true” downlog at 4400.5 m WRF |
| 3 Nov | 0536 | Wireline heave compensator optimization performed |
| 3 Nov | 0705 | Reach total depth of 4750.1 m WRF (bottom of hole not tagged on this down pass) |
| 3 Nov | 0706 | Begin uplog |
| 3 Nov | 0806 | Begin second downlog (from 4486.5 m WRF) |
| 3 Nov | 0906 | Begin second uplog (from 4752.4 m WRF; tagged bottom) |
| 3 Nov | 1012 | Second uplog finished at 4412.8 m WRF after logging through the seafloor |
| 3 Nov | 1310 | AMC II tool string rigged down |
| 3 Nov | 1344 | FMS-sonic tool string rigged up |
| 3 Nov | 1410 | FMS-sonic run into hole |
| 3 Nov | 1634 | Begin logging downward from 4400.1 m WRF; WHC was assessed briefly and was completed at 1710 h |
| 3 Nov | 1746 | Tool string reached total depth 4757.2 m WRF |
| 3 Nov | 1748 | Begin first pass |
| 3 Nov | 1835 | End of first pass (ran calipers just into casing) |
| 3 Nov | 1836 | Run tool string back down to total depth |
| 3 Nov | 1901 | Begin second pass |
| 3 Nov | 1952 | End of second pass |
| 3 Nov | 2220 | Tool string back to the surface |
| 3 Nov | 2245 | FMS-sonic rigged down and logging operations concluded |
HRLA = High-Resolution Laterolog Array, AMC II = adapted microbiology combination II, FMS = Formation MicroScanner. DEBI-t = Deep Exploration Biosphere Investigative tool. WHC = wireline heave compensator. Time is reported as ship local (UTC – 3 h).
