7132/2-2

General

Well 7132/2-2 was drilled to test the Gjøkåsen Deep prospect on the Signalhornet Dome on the Finmark Platform in the Barents Sea. The Gjøkåsen Deep is the second well on the structure; it was planned and drilled back-to-back with the first well, 7132/2-1 Gjøkåsen. The primary exploration target for Gjøkåsen Deep was to prove petroleum in reservoir rocks from the Early to Late Triassic Age (the Snadd, Kobbe and Havert formation). The secondary exploration target was to prove petroleum and reservoir potential in the lower Havert formation (Early Triassic Age).

Operations and results

Wildcat well 7132/2-2 was spudded with the semi-submersible installation West Hercules on 6 January 2019 and drilled to TD at 3528 m in the Permian Røye Formation. After drilling the top hole to 600 m the well was suspended from 14 January to 9 February when the rig was engaged in operations at 7132/2-1. An influx was registered by high gas readings at surface while circulating bottoms up from TD at 3400 m, with a gas peak of 52.3% before the well was shut in. No volume increase was observed in the active system. The well was drilled with seawater and hi-vis sweeps down to 601 m, with KCl/polymer/GEM mud from 601 to 1851 m, and with Innovert oil-based mud from 1851 m to TD.

In the primary exploration target, well 7132/2-2 encountered 25 metres of sandstone reservoir with moderate to good quality in the Snadd formation (Carnian Age), 17 metres of sandstone reservoir with poor to moderate quality in the Kobbe formation and 26 metres of sandstone reservoir with poor quality in the upper Havert formation. Sandstone reservoir was also encountered in the Klappmyss Formation (Early Triassic Age) in a thickness of 17 metres with poor quality. In the secondary
