Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 30/9-B-18 A is a production side-track from observation well 30/9-B-18 on the 30/9-1 Oseberg Discovery in the North Sea. The main objective for Well 30/9-B-18A was oil production from a planned 1200 metres horizontal section in the Oseberg, Etive and Lower Ness Formations.
The NSO-1 geochemical standard oil was produced from 30/9-B-18 A.
Operations and results
Development well 30/9-B-18 A was kicked off at 3344 m in well 30/9-B-18 on 26 September 1992. It was drilled from the Oseberg B platform to TD at 4982 m (2761 m TVD) m in the Middle Jurassic Ness Formation. The target of the well was on the Oseberg Alpha Structure approximately 3 km south-east of the Oseberg B platform. It was drilled horizontally (between 88 and 93 deviation) from ca 3850 m in the Oseberg Formation To TD at 4982 m in the Ness Formation. The well was drilled with oil based Safemul mud from kick-off to TD.
Total drilled length of Oseberg, Etive and Lower Ness in the horizontal well is ca 1130 m, in line with the prognosed 1200 metres.
No cores were cut in this well. No wireline pressures were taken, and no wireline fluid sample was taken.
The well was completed as a producer on 8 December 1992.
Testing
The well was completed with 15 perforation intervals between 3831 m and 4912 m (2762.2 m TVD and 2759.5 m TVD) in the horizontal sections in the lower Ness and Oseberg-Rannoch-Etive (ORE) formations. Production testing measured flow rat

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.
