Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 6406/3-10 A is a geological side-track to well 6406/3-10 on the Halten Terrace in the Norwegian Sea. The primary objective was to appraise the oil discovery in the Garn, Ile and Tilje formations made by the 6406/3-10 well. The 6406/3-10 well also found hydrocarbons in the re Formation, but it was not fully tested. A secondary objective with the side-track was therefore to drill deeper into re for a more complete evaluation of this formation.
Operations and results
Appraisal well 6406/3-10 A was kicked off at 2281 m in the main well on 14 July 2021. It was drilled with the semi-submersible installation DeepSea Aberdeen to TD at 5190 m (4884 TVD) m in the Early Jurassic re Formation. Operations proceeded without significant problems. The well was drilled with Innovert NS oil-based mud from kick-off to TD.
The Bergknapp side-track 6406/3-10 A confirmed an oil column of 6 meters in Garn Formation, with a sandstone layer of 62 meters net of moderate to poor reservoir quality. The oil-water contact (OWC) was found at 4408 m (4102 m TVD). This could be an oil-down-to (ODT) contact in case of a sealing layer underneath.
An oil column of 2.5 m was confirmed in the upper sandstone in the Ile Formation.
The Tilje Formation had oil in three zones: an upper 15 m zone with OWC/ODT at 4764 m (4458 m TVD), a thin sandstone at 4793 m as confirmed by sampling, and an 8-meter oil column with OWC/ODT at 4821.5 m (4516 m TVD). There were no oil shows other than in the hydrocarbon-bearing formations in the Fangst and B t Groups.
A total of 318.5 m core was recovered in 5 core runs. Garn/N

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.
