Well history

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

General

Well 24/9-6 was drilled to appraise the 24/9-5 discovery and is located 2.2 km to the east of the 24/9-5 well location. Well 24/9-5 encountered a thin, 5.9 m net Balder Sandstone reservoir. It was considered not to be optimally placed for the Balder Formation objective and no production tests were made. Instead well 24/9-6 was drilled as an immediate appraisal in an optimum location. Mapping indicated that sandstone presence within the Balder Formation could be identified by gross Balder Formation thickening and by an associated seismic amplitude anomaly, believed to be a direct hydrocarbon indicator. Well 24/9-6 was located close to the centre of the Balder Formation interval thickening in a position where the seismic amplitude anomaly was best developed

Operations and results

Appraisal well 24/9-6 was spudded with the semi-submersible installation West Delta on 1 February 1994 and drilled to TD at 2255 m in the Paleocene Heimdal Formation. No significant technical problems were reported from the operations. The well was drilled with seawater down to 1279 m, with KCl/polymer/glycol from 1279 m to 1957 m, and with KCl/polymer mud from 1957 m to TD.

The Balder Formation was encountered at 1917 m with two massive Intra Balder Formation sandstone sequences with a total net thickness of 49.5 m (prognosis 25 m). The first Intra Balder Formation sandstone was encountered at 2010.5 m, the second at 2034 m. A thin (0.5 m) oil-bearing sandstone was encountered at 2004.0 m just above the upper massive sandstone. The upper massive sandstone was hydrocarbon bearing all through down to the base at 2022 m, without any OWC seen. The lower massive sandstone proved to be water bearing. Thin sandstones in the interval 2029.0-2033.0 m had good shows on core. The highest known water was observed at 2034.0 m.

Analysis of a PVT sample from 2012.0 m showed the oil gravity to be 32 deg API with a gas/oil ratio (GOR) of 105 Sm3/Sm3. PV

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.
