7324/7-3 S

06/04/2016 OMV Norge AS, operator of production licence 537, is in the process of completing the drilling of appraisal well 7324/7-3 S on the 7324/8-1 (Wisting) oil discovery.

The well was drilled about 310 km north of Hammerfest.

The discovery was proven in reservoir rocks from the Middle and Early Jurassic (upper Realgrunnen subgroup) in 2013. Before well 7324/7-3 S was drilled, the operator's resource estimate for the Wisting area was between 32 and 80 million standard cubic metres (Sm3) of recoverable oil equivalents.

The objective of the well was to confirm the size of the 7324/8-1 discovery in the "Wisting Central Sør" and "Wisting Central Vest" segments. An additional objective was to test whether the well can be drilled horizontally in the shallow reservoir approximately 250 m below the seafloor, as well as to formation-test the Stø formation.

The well was drilled with a horizontal section of about 1400 metres. It encountered sandstones in the Stø and Fruholmen formations. The "Wisting Central Sør" segment has good reservoir properties in the Stø formation and moderate reservoir properties in the Fruholmen formation. Reservoir quality in the Stø formation in the "Wisting Central Vest" segment is also good. The oil/water contact was not encountered. The estimate of the discovery size will be updated based on evaluation of the new well data. The result will be important for further maturation of the Wisting area, as regards a potential development.

Extensive data acquisition and sampling have been carried out. A successful formation test was conducted in the Stø formation in the "Wisting Central Vest" segment. Maximum production rates were 762 Sm3 of oil and 48 310 Sm3 of associated gas per flow day through a 104/64-inch nozzle opening. The gas/oil ratio is 73 Sm3/Sm3. The formation test revealed production and flow properties that were mainly good.

This is the fifth exploration well in production licence 537. The licence was awarded in the 20th licensing round in 2009.

Appraisal well 7324/7-3 S was drilled to vertical and measured depths of 673 and 2314 metres, respectively, below the sea surface, and was terminated in the Stø formation from the Middle Jurassic Age. Water depth in the area is 402 metres. The well will now be permanently plugged and abandoned.

The well was drilled by Transocean Spitsbergen.
