Engie E&P Norge, operator of production license 636, is in the process of completing the drilling of wildcat well 36/7-4. The well proved oil and gas.
The well was drilled six kilometres northeast of the Gjoa field and 55 kilometres southwest of Floro.
The objective of the well was to prove petroleum in Early Cretaceous reservoir rocks (Agat formation).
The well encountered an approx. 50-metre gas column and 60-metre oil column in the Agat formation. Reservoir quality ranges from very good in the top section to good in the lower section.
Preliminary estimation of the size of the discovery is between 4.3 – 11 million standard cubic metres (Sm3) of recoverable oil equivalents.
The well was formation-tested. The maximum production rate was 1.3 million Sm3 gas per flow day through a 76/64-inch nozzle opening. The gas/oil ratio is approx. 16,000 Sm3/Sm3. The formation test generally showed very good production and flow properties. Extensive data and samples were collected.
The licensees will consider a tie-in of the discovery to existing infrastructure on the Gjoa field.
36/7-4 is the first exploration well in production licence 636. The licence was awarded in APA 2011.
The well was drilled to a vertical depth of 2702 metres below the sea surface, and was terminated in the Åsgard formation in the Lower Cretaceous.
Water depth at the site is 349 metres. The well will now be permanently plugged and abandoned.
The well was drilled with the Transocean Arctic drilling facility.
