Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 16/3-U-1 A is a geological and geo-mechanical side-track to 16/3-U-1 on the south-eastern end of the Johan Sverdrup Field on the Utsira High in the North Sea. The reservoir in this part of the field is below seismic resolution. The primary objective of the primary well and side-track was to investigate sand presence, thickness and quality. Secondary, to investigate horizontal well drilling and high angle hole time-stability in the Draupne shales.
Operations and results
Wildcat well 16/3-U-1 A was kicked off below the 13 3/8” casing at 1135 m in the primary well on 24 December 2016. It was drilled with the semi-submersible installation Deepsea Atlantic, down-dip towards the south-east to TD at 2882 m (1965 m TVD) in Basement rock. Operations proceeded without significant problems. The well was drilled with Carbosea oil-based mud from kick-off to TD.
Top Draupne Formation was penetrated at 2578 m (1939 m TVD), while the Intra Draupne Formation sandstone was encountered at 2763 m (1955 m TVD), and Basement at 2861 m (1963 m TVD). <span lang=EN-GB style='mso-ansi-language: E

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.
