Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 6406/12-G-1 H is an extension of an observation well for the 6406/12-3 A (Bue) oil discovery. The well was drilled on the Fenja field on the southern end of the Halten Terrace in the Norwegian Sea. The primary objective of the exploration section was to confirm oil in Rogn Formation sandstones in the north-eastern part of the Fenja Field, and thereby reduce uncertainty in the resource estimates. Secondary objective was to test Intra Melke Formation sandstones.
Operations and results
A 9 7/8" pilot hole designated 6406-12-U-1 was drilled down to 1240 m to check for shallow gas. No shallow gas was detected.
Well 6406/12-G-1 H was spudded with the semi-submersible installation West Phoenix on 3 May 2020 and drilled to TD at 4235 m (3734 m TVD) in Middle Jurassic (Callovian) claystone belonging to the Melke Formation. The well was drilled in 67.7 days vs. the planned 38.4 days with 13 days (19%) WOW and 8.4 days (12.3%) NPT. Main source of WOW was related to running the 20" casing and while running the 13-5/8" casing. NPT was mainly due to loosing and fishing of Wireline tool string, as well as reduced crew availability due to Covid-19 outbreak on the rig. The well was drilled with seawater and hi-vis pills down to 1244 m, with RheGuard oil-based mud from 1244 to 2477 m, and with Exploradrill oil-based mud from 2477 to TD.
Well 6406/12-G-1 H did not encounter reservoir rocks in the primary Bue/Rogn Formation target. The well did however 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.
