Well history

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

General

Well 30/9-8 was drilled on the Oseberg Omega structure, which is located between the Gamma structure to the east and the B structure to the west, and extends northwards into 079 license area. The main target of the well was sandstones in the Middle Jurassic Brent Group. The primary objectives were to prove the extension of the Omega oil column into license 104, find the fluid contacts, and test communication and reservoir relationship with the Omega North and B prospects. The well was planned to drill approximately 50 m into the Dunlin Group at a final depth of approximately 3182 m RKB.

Operations and results

Well 30/9-8 was spudded with the semi-submersible installation Polar Pioneer on 29 July 1989 and drilled to TD at 1060 m in presumed Miocene sediments of the Hordaland Group. The well was drilled using seawater and high viscosity pills with returns to the seabed.

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

After setting of the 13 3/8" casing to 1044 m the well was suspended on 2 August while the rig left for work on another contract (TOGI pull-in operation). The well is classified as dry.

Testing

No drill stem test was performed.

About this data

Norwegian Offshore Directorate (Sodir) FactPages, mirrored nightly and used under the Norwegian Licence for Open Government Data (NLOD). Depths are metres along the wellbore from the kelly bushing unless a row gives its own unit; older cores are filed in feet. A zero the Directorate files for an unmeasured pressure, density, or temperature is shown as a dash.
