Well history

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

General

Well 6507/4-2 S was drilled to test the Dvalin prospect on the Revfallet Fault Complex between the Victoria and rfugl discoveries in the Norwegian Sea. The primary objective for the well was to prove hydrocarbons in the Middle Jurassic Garn Formation in the Fangst Group. The secondary objectives were to prove hydrocarbons in the Cretaceous Lysing and Lange Formations.

Operations and results

Wildcat well 6507/4-2 S was spudded with the semi-submersible installation Deepsea Aberdeen on 20 February 2021 and drilled to TD at 4485 m (4430 m TVD) m in the early Jurassic Ror Formation. Non-production time was 19.7 days (22%) mainly due to ruptured BOP control Multiplex cable during a WOW period. This occurred during logging operations in the 8 1/2" section. The well was drilled with seawater and hi-vis pills down to 1500 m and with Innovert NS oil-based mud from 1500 m to TD.

The well proved gas in the Garn Fm, with no proven gas-water contact, it proved gas/condensate in the Lysing Fm with gas-water contact at 2923.5 m (2915 m TVD), and it proved gas and oil in four differently pressured sand layers in the Lange Fm. No hydrocarbon contacts were identified in the Lange Formation. Shows were observed in the hydrocarbon bearing sands in the Lange and Garn formations. The deepest show in the Garn Formation was at 4363 m. In the Lysing Formation no shows were observed.

Three cores were cut in succession from 4262.4 to 4326.7 m in the Garn Formation. Total recovery was 100%. MDT fluid samples were taken in the Lysing Formation at 2897.5 m (gas condensate), 2909.2 (gas condensate) and 2961.5 m (water), in the Lange Formation at 3597.6 m (wet gas), 3701.6 m (oil) and 3822.3 m (oil),

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.
