Well history

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

General

Well 16/3-U-1 B 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-tracks was to investigate sand presence, thickness and quality. Secondary, to investigate horizontal well drilling and high angle hole time-stability in the Draupne shales. As part of the secondary objective the first side-tracked bore hole 16/3-U-1 A should be left open for 48 hours and then re-entered. After an unsuccessful re-entry well bore 16/3-U-1 A was abandoned and side-track 16/3-U-1 B was initiated. Final TD in this side-track was set to a location between the primary wellbore and the first side-track in order to penetrate the field OWC.

Operations and results

Well 16/3-U-1 B was kicked off from 16/3-U-1 A below the 13 3/8" shoe at 2115 m on 10 January 2017. It was drilled with the semi-submersible installation Deepsea Atlantic, down-dip towards the south-east of the primary well bore to TD at 2665 m (1963 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 2515 m (1937 m TVD), while the Intra Draupne Formation sandstone was encountered at 2598 m (1952 m T
