LONDON – The semisubmersible West Phoenix is concluding a current wildcat well for Neptune Energy on the Fenja field in the Norwegian Sea.
According to the Norwegian Petroleum Directorate (NPD), well 6406/12-G-1 H, drilled in 322 m (1,056 ft) of water in license PL586, is an extension of an observation well for the 2014 6406/12-3 A (Bue) oil discovery.
The location is around 120 km (74.6 mi) north of Kristiansund.
Bue’s oil discovery was proven in the Rogn formation in Upper Jurassic reservoir rocks. The main purpose of the present well was to reduce uncertainty in the resource estimate.
While the well 6406/12-G-1 H did not encounter reservoir rocks in either the primary or secondary exploration target, it did penetrate a total oil column of 38 m (125 ft) just above the secondary target in the lower part of the Mid-Jurassic Intra-Melke formation, of which around 20 m (65.6 ft) were of moderate to good reservoir quality, the NPD said.

Preliminary analysis has led to a downgrade of recoverable reserves from the original Bue discovery to 0.2-1.6 MMcmoe, while the estimate for the new oil find is 0.5-3.2 MMcmoe.
The licensees will consider tying the discoveries into existing infrastructure on Fenja, currently being developed as a long-distance subsea tieback to the Njord complex.
After the rig has temporarily P&A’d the well it will head to Ølen for a shipyard stay.
