General
The Flyndre (1/5-1) well was drilled on a structural high situated in the Feda Graben of the North Sea close to the UK border.& At the commencement of the well the principle objective horizons were the Paleocene and Jurassic sand sections which had produced oil in the UK 30/13-2 well and the NO 2/7-3 wells respectively.& It was estimated that at Paleocene depth the structure was an irregular dome about 4 miles in diameter, with 12 square miles of closure and 290 ft (88.4 m) of vertical relief while at Jurassic depth the structure was a NW-SE trending anticline 4.5 miles by 3.5 miles with 12 square miles of closure at 190 ft (57.9 m) of vertical relief. Planned TD was 15000 ft (4572 m), Triassic sands, or the Zechstein Group, whichever came first.
Operations and results
Wildcat well 1/5-1 was spudded with the semi-submersible installation Ocean Viking on 12 October 1973. The well was drilled to 491 m in the Nordland Formation. When running 20" casing the casing got stuck. After an unsuccessful fishing operation the well was permanently abandoned on 19 October 1973 as a junk well. No cores were cut and no wire line fluid samples were taken.
Replacement well 1/5-2 was spudded 15 m away in a 320 deg true direction.
