General

Well 33/12-3 was drilled on the Statfjord structure in the Tampen Spur area. It was designed to test the erosional escarpment on the east flank of the structure for possible trapping of hydrocarbons in an area downfaulted to the Statfjord Field pay section to the west. Primary objectives of the well were the Early Jurassic Statfjord Group sands and possible Middle Jurassic Brent Formation sands.

Operations and results

Appraisal well 33/12-3 was spudded with the semi-submersible installation Nordskald on 23 April 1975 and drilled to 1725 m in the Paleocene Balder Formation. At this depth irreparable damage to the wellhead led to the decision to abandon the well.

No cores were cut and no wire line fluid samples were taken.

The well was permanently abandoned on 16 May 1975 as junk well. The rig was moved 30 m and replacement well 33/12-4 was initiated.

Testing

No drill stem test was performed.
