Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 34/10-27 was drilled on the Gullfaks Field to investigate and drain possible shallow gas sands between 342 to 347 m at the platform A location on the Gullfaks Field.
Operations and results
Well 34/10-27 was spudded with the semi-submersible installation West Venture on 2 December 1985 and drilled to TD at 482 m in Pliocene sediments in the Nordland Group. No significant problem was encountered in the operations. The well was drilled with water based mud.
Top Pliocene was encountered at 290 m. Electric logs through the 12 1/4" section showed only 1 - 1.5 m of possible shallow gas sand between 345.5 and 347.1 m.
No cores were cut. The RFT tool was run in the gas sand for pressure points but no fluid samples were taken. Cuttings samples were taken every 5 m from 270 m to TD.
The well was suspended on 14 December 1985.
Testing
Due to very thin gas sand 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.
