General

Well 30/3-3 was drilled on the Lomre Terrace between the Veslefrikk and Brage oil fields. The primary objective was sandstone of the Middle Jurassic Brent Group, the secondary objective was sandstone of the Early Jurassic Dunlin Group.

Operations and results

Wildcat well 30/3-3 was spudded with the semi-submersible installation Ross Isle on 2 April 1983 and drilled to TD at 3419 m in the Early Jurassic Statfjord Formation. No significant problem was encountered in the operations. The well was drilled with spud mud down to 969 m, with gypsum/lignosulphonate/CMC from 969 m to 2861 m, and gel/lignosulphonate/CMC from 2861 m to TD.

The well was dry. Oil shows were described on sandstone cuttings from 3035 - 3037 m in the uppermost Etive Formation and from 3185 m to TD. Sandstone side wall cores from the same interval had no shows, and geochemical extracts proved only immature hydrocarbons from in-situ shales.

One core was cut in the Ness Formation from 2979 m to 2992.5 m. No wire line fluid samples were taken.

The well was permanently abandoned on 30 May 1983 as a dry well.

Testing

No drill stem test was performed.
