Vaar Energi's Success on the Goliat Ridge

Vaar Energi, the operator of the Goliat oilfield in Norway's Barents Sea, has drilled another successful appraisal well, marking the third consecutive discovery in a new geological play known as the Goliat Ridge. The discoveries, named Countach, Countach appraisal, and Zagato, collectively hold a gross estimated recoverable resource with a high case of 100 million barrels of oil equivalent.

Resource Estimates for Zagato

The most recent success was an appraisal of the Zagato discovery. Vaar Energi reported that the latest appraisal well, Zagato North, found a gross estimated recoverable resource of 3 million boe. In contrast, the Norwegian Offshore Directorate provided a broader estimated recoverable resource range of 18 million to 64 million boe for the Zagato discovery, which includes the previous Zagato South well.

Future Drilling Plans

Further appraisal drilling is planned, with a well called Goliat North scheduled for the fourth quarter. This will be followed by a sidetrack and a well test of the Zagato South appraisal, indicating continued exploration and evaluation activities in the area.

Well Details and Geological Findings

The latest well, 7122/8-4 S, was drilled in Block PL 229, located 10 kilometres north of the Goliat field, using the semi-submersible rig COSL Prospector. It encountered an 11-metre oil column in the Tubaen Formation within the Realgrunnen subgroup, characterized by good reservoir quality. The oil-water contact was identified at 1523 metres below sea level, and the water depth at the site is 406 metres. The well has been permanently plugged and abandoned following data collection.

Development Considerations and Partnership

Vaar Energi is evaluating the possibility of a tie-back development for the Goliat Ridge discoveries to the existing Goliat FPSO (Floating Production, Storage, and Offloading unit). The license partnership consists of Vaar Energi with a 65% stake and Equinor holding the remaining 35%.
