Well history

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

General

Well 24/9-7 was drilled on the Hamsun prospect located immediately to the west and south west of the Gekko structure in PL203 (Figure 1). The prospect was a "horse-shoe" shape around the Grieg structure, drilled by wells 24/9-5 and 24/9-6 in 1993 and 1994. The Hamsun prospect was defined by the recognition and interpretation of a series of distinct seismic anomalies and mapped as a sandstone injection complex, sourced from early Eocene Hermod Formation sands. These anomalies were interpreted to represent oil-filled, highly porous sandstone dykes and sills. Several well bores were proposed to test the prospect. The prime vertical well was planned to intersect the thickest part of the injection complex to test bright amplitude, low acoustic impedance seismic reflectors interpreted to represent major sandstone dyke complexes. A sidetrack well bore was planned depending on the results of the first well.

Operations and results

A total of four wells were drilled from the surface location for 24/9-7 (the planned vertical well, an unplanned down-dip sidetrack 24/9-7 A, the planned up-dip sidetrack 24/9-7 B and a further unplanned lateral sidetrack 24/9-7 C). Taken as a whole, the four well bores took a total of 43.11 days to drill. All were drilled from the semi-submersible installation Deepsea Delta. No significant problems were encountered in the operations. Well 24/9-7 was drilled with seawater down to 953 m. From this depth to TD 24/9-7 and all sidetracks were drilled with Versavert oil based mud.

The prime vertical well bore 24/9-7 was spudded on 2 March 2004 and drilled to TD at 2280 m in the Late Paleocene Heimdal Formation. The well was plugged back for sidetracking on 24 March 2004. Well 24/9-7 A was kicked off at 1500 m and drilled to TD at 2277 m (2216.9 m TVD) in Heimdal Formation sandstone. The well was plugged back for a second sidetrack on 28 March 2004. Well bore 24/9-7-B was sidetracked from 1060 m and

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.
