Well history

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

General

Well 16/3-6 was drilled on the eastern part of the Johan Sverdrup Field on the Utsira High in the North Sea. The primary objective was to appraise the eastern part of the Johan Sverdrup Field between wells 16/2-13 S and 16/3-4. These two wells are located 5 km apart and found different Jurassic sequences and no oil water contact. Well 16/3-6 was drilled to determine which Jurassic sequences were present at this position as well as oil water contact, thickness of the sequences and depth to top reservoir.

Operations and results

A 9 7/8" pilot hole was drilled from seabed 706 m to check for shallow gas. No shallow gas was seen. Appraisal well 16/3-6 was spudded with the semi-submersible installation Bredford Dolphin on 10 June 2013 and drilled to TD at 2050 m in fractured granitic basement. No significant problem was encountered in the operations. The well was drilled with spud mud down to 698 m and with Performadril water based mud from 698 m to TD.

Top Draupne Formation/BCU was encountered close to prognosis at 1924 m. A well-defined 15-meter thick Draupne Formation shale was penetrated above 24 meters of excellent quality Late Jurassic Intra-Draupne Formation sandstone. The Draupne Formation shales are of late Volgian to early Valanginian age. The Intra-Draupne Formation sandstones were encountered at 1939 m. They are of early Kimmeridgian to ?late Kimmeridgian/early Volgian age and rest directly on solid granitic basement rocks at 1964.5 m. No middle Jurassic sequence was present as in the neighbouring well 16/2-13 S. The oil water contact was established at 1951 m, 4 meters deeper than predicted. Oil shows were described in the interval from 1925 m in the Draupne shales to 1956 m, 5 m below the oil water contact; no ot
