6406/6-6 S

Wildcat well 6406/6-6 S was spudded with the semi-submersible installation Scarabeo 8 on 16 August 2018 and drilled to TD at 4911 m in the Early Jurassic Ror Formation. A water flow caused a well control situation when drilling through a fault at 2324 m. Otherwise, operations proceeded without significant problems. The well was drilled with seawater and hi-vis pills down to 1300 m, with Glydril mud from 1300 to 2007 m, with EMS-4600 oil-based mud from 2007 m to 2367 m, and with Rheguard oil-based mud from 2367 m to TD.

The Garn Formation was encountered at 4500 m (4433 m TVD) and the Ile Formation at 4640 m (4569.2 m TVD). Garn and Ile are separated by claystone and siltstone belonging to the Not Formation from 4608.5 to 4640 m (4642 to 4674 m TVD). The Tofte Formation was penetrated from 4852.5 to 4880 m (4886.2 to 4914 m). The Fangst Group contained hydrocarbons, mainly in degraded reservoir facies. Gas was sampled in the best reservoir over the upper Ile formation. Pressure acquisition attempts in the Garn and upper Ile formations could not confirm the presence of a connected column. The lower Ile and Tofte formations were of good to excellent reservoir quality but water bearing. No visible hydrocarbon shows were observed in cuttings or on core.

One core was cut from 4654 to 4681 m in the Tofte Formation with 101.1% recovery. Fluid samples were taken at 4703.68 m (gas), 4720,93 m (water with gas) 4741.49 m (gas), and 4749.0 m (water with gas)

The well was permanently abandoned on 16 November 2018 as a gas discovery
