Wintershall Norge’s 6407/1-5 S appraisal well in the North Sea encountered a 39-m (127-ft) thick oil column in the Garn formation with reservoir and reservoir quality as expected. The oil-water contact in the well is the same as in the discovery well, and pressure data indicates communication between north and south. With that, the discovery is delineated to the north.

Preliminary calculations confirm earlier resource estimates, though at the upper end of the discovery estimate. The 6407/1-5 S well’s purpose was to delineate discovery 6406/3-8 to the north.

A successful formation test has been carried out over a short reservoir interval. The maximum production rate was, respectively, 140 cu m of oil and 20,300 cu m of gas per day through a 40/64-in nozzle opening.

The licensees will now assess alternative development solutions for the discovery.

The well was drilled around 20 km east of the Kristin field in the Norwegian Sea and about 8.0 km northeast of discovery well 6406/3-8.

The well was drilled to a total depth of 4,133 m (13,559 ft) below the sea surface and terminated in the Tilje formation in the Lower Jurassic. The sea depth is 297 m (974 ft). The well will now be permanently plugged and abandoned.

Well #6407/5-1 S was drilled by the drilling facility Borgland Dolphin, which will now head to license 102 C to drill 25/5-D-1 H Atla, where Total E&P Norge AS is the operator.
