Victoria University Antarctic Research Expedition Science and Logistics Reports 1998-99: VUWAE 43

Casing and hole completion

Casing and hole completion

HQ casing (with barrel assembly later drilled out) was cemented at 199.3 m bsf. This casing was cut off around 70? m bsf [confirm with drilling manager's report] leaving approximately 130m of casing cemented in the well. The cut off HQ casing was with- drawn to expose the formation above 70? m bsf for down hole logging but immediately bridged at the 25 m and probably collapsed down to the casing cut off.

The hole was sealed above 25 m bsf with 165 litres of grout on December 1?

The sea riser casing was cut off about 1-1.5 m bsf leaving approximately 12.5 m of casing page break cemented below the sea floor.
