Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 2/7-27 S was drilled on the Embla structure in the southern North Sea. The objective was to drill to replace the abandoned 2/7-23 S well as a production well in the Embla reservoir. Well 2/7-27 S would thus be drilled as close as possible to the 2/7-23 S well path and to the same bottom hole location. By this it was anticipated that the extensive core data recovered in the 2/7-23 S would be applicable to the production data to be gained from the 2/7-27 S. The 2/7-23 S had earlier confirmed the presence of hydrocarbon bearing sandstones originally discovered in the 2/7-9 (1974), and later tested in the 2/7-20 (1988) and 2/7-21 S (1989) wells, but was abandoned before well testing could be performed.
Operations and results
Appraisal well 2/7-27 S was spudded with the semi-submersible installation West Delta on 9 November 1991 and drilled to TD at 4801 m (4452 m TVD) in pre-Jurassic rocks. It was drilled deviated from a fifteen slot production template located at the site of the planned Embla production facilities. Drilling problems with stuck pipe were encountered in the 12 1/4" hole section at 3470 m, forcing a technical sidetrack from 2972.7 m. Unlike previous Embla wells, the 2/7-27S was drilled using water based mud throughout. It was drilled with seawater and hi-vis pills down to 573 m, with KCl/polymer mud from 573 m to 3791 m, with Baranex-Thermathin mud from 3791 m to 4500 m, and with a Thermadrill/Baranex high temperature mud system from 4500 m to TD.
The 2/7-27 S well encountered top Mandal Formation at 4476 m and top pre-Jurassic reservoir at 4483.3 m (4177.6 m TVD) with the same reservoir stratigraphy as the 2/7-23S. However, although the wells are only 46.5 m apart at the Base Cretaceous Unconformity, th

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.
