Pressure Core Analysis Tools |
Cores 23C, 24C, and 25C taken with the Fugro Corer (FC) core barrel had low recoveries of disturbed sediment. Core 26R was a pressure core taken with the Hyacinth Rotary Corer at or just above the depth of the BSR (383 mbsf) which came up with 140 bar pressure and was successfully transferred. Core 27P was an unsuccessful attempt to get a pressure core just below the BSR.
Plans:
Take an FC core with a temperature measurement as Core 27C at 387 mbsf, then follow with an HRC pressure core and a piezoprobe measurement. Drill down to 440 mbsf and take FC core if time permits. Otherwise condition hole and make ready for wireline logging.
