RWE Dea Norge Makes Gas Discovery in Norwegian Sea

A gas discovery of up to 13 billion standard cubic meters of recoverable gas has been made near the Heidrun field in the Norwegian Sea, according to a statement made on Tuesday by the Norwegian Petroleum Directorate.

RWE Dea Norge, operator of production licence 435, is in the process of completing the drilling of wildcat well 6507/7-15 S, which has made the discovery. 
The well was drilled about 2 miles (3.5 kilometers) west of the 6507/7-14 S gas discovery made on the same license in 2010, and 9 miles (15 kilometers) northwest of the Heidrun field in the Norwegian Sea.
The primary exploration target for the well was to prove petroleum in Middle Jurassic reservoir rocks (the Fangst group). The secondary exploration target was to prove petroleum in reservoir rocks from the Early Cretaceous Age (the Lange formation) and Early Jurassic Age (the Tilje formation).
Gas was proven in sandstones in the Garn and Ile formation (the Fangst Group) in a gross column of about 460 feet (140 meters). Preliminary estimates place the size of the discovery between 4 and 13 billion standard cubic meters of recoverable gas. In addition, small amounts of gas were proven in the Lange and Tilje formations.
The well was not formation-tested, but extensive data acquisition and sampling have been carried out which will provide valuable information for future production of the gas discoveries in the production license.
The licensees in production license 435 will consider producing the discovery together with the 6507/7-14 S discovery, to the Heidrun field.
The well is the second exploration well on production license 435, which was awarded in APA (Awards in Pre-defined Areas) 2006.
The well was drilled to a vertical depth of 14,900 feet (4,534 meters) below the sea surface, and was terminated in the Tilje formation in the Lower Jurassic.
Water depth at the site is 1,300 feet (399 meters). The well will now be permanently plugged and abandoned.
Well 6507/7-15 S was drilled by the West Alpha (MW semisub) drilling facility, which will now proceed to production license 477 in the Norwegian Sea to drill wildcat well 6506/11-9 S, where Centrica Resources (Norge) is the operator.
